⚗️ Upgrade Guide

Weapon Evolution Paths

I've put way too many hours into this game and tbh the weapon evolution system is the one thing you really need to get right, pick the wrong branch and you're basically stuck forever because there's no respec option and I learned that the hard way ugh, this guide covers every upgrade tree and all the materials you need and which path actually works for your build and stuff like that

okay so the whole weapon evolution thing in Phantom Blade Zero is kind of different from other games tbh, basically every weapon goes through three tiers of upgrades and when you hit the final tier you get two branching paths to choose from, unlike those games where a +5 sword is just better than a +4 and that's it, PBZ actually lets you customize your weapon's stat profile and passive effect and honestly choosing the right evolution path matters just as much as picking the right weapon in the first place, I literally wasted like 15 Primal Shards on a branch I ended up hating so yeah don't do what I did, anyway here's everything you need to know about the upgrade system and how it works and which paths are actually worth taking and which ones are kind of a trap imo

Evolution Basics

so every weapon starts at Tier 1 which is the base form and you need materials to upgrade it obviously, each tier gives you better stat bonuses and sometimes unlocks new passive abilities which is where things get interesting, here's basically how the whole system works

TierLevel RangeMaterials NeededStat Bonus per LevelSpecial
Tier 1 (Base)1-15Scrap Metal, Rusted Ore+2 Attack, +1% Sha-Chi GenWeapon passive unlocked at Level 5
Tier 2 (Refined)16-30Refined Ore, Phantom Essence+3 Attack, +2% Sha-Chi GenPhantom Edge slot unlocked at Level 20
Tier 3 (Evolved)31-45Primal Shard, Soul Fragment+5 Attack, +3% Sha-Chi GenBranching passive choice at Level 35
Important: okay here's the thing about evolution materials and nobody told me this when I started, they're shared across ALL your weapons which sounds fine until you realize the cost literally goes up for each weapon you upgrade, your first Tier 3 weapon costs 15 Primal Shards but your second one costs 30 and your third costs even more, tbh you cannot max every weapon in a single playthrough so plan carefully or you'll end up with a bunch of half-upgraded weapons that all kind of suck and you'll be stuck with them for the rest of the run

Materials and Where to Actually Find Them

MaterialUseCommon SourcesFarming Route
Scrap MetalTier 1 upgrades (Levels 1-10)Regular enemies, breakable objectsChapter 1 courtyard, respawns on rest
Rusted OreTier 1 upgrades (Levels 11-15)Elite enemies, mining nodesUnderground Cavern, 6 nodes per run
Refined OreTier 2 upgrades (Levels 16-25)Minibosses, ore veins in Chapter 2+Forgotten Temple, 4 nodes, 2 minibosses
Phantom EssenceTier 2 upgrades (Levels 26-30)Boss drops, chestsBoss rush mode, guaranteed 2 per boss kill
Primal ShardTier 3 upgrades (Levels 31-40)Story bosses, hidden bossesSeven Judgments, guaranteed 5 on first kill
Soul FragmentTier 3 upgrades (Levels 41-45)Post-game bosses, NG+NG+ boss rush, 1 per boss, unlimited
Farming Priority: honestly Refined Ore is the biggest bottleneck in a normal playthrough and I'm not even exaggerating, before you start Chapter 3 farm the Forgotten Temple route which has 4 ore veins and 2 minibosses, stockpile at least 40 Refined Ore and that'll cover two Tier 2 weapons comfortably, I made the mistake of not farming enough and had to go back and grind for hours ugh, just get it done early and thank me later, seriously this is probably the single most important farming tip in the whole guide

Weapon Evolution Trees

Sword Evolution

Jagged Steel

so this is the starting sword and honestly it's probably the most versatile weapon in the whole game, balanced stats and bleed buildup right from the start with the most flexible evolution tree of any weapon imo, if you're not sure what to invest in just stick with Jagged Steel and you'll be fine tbh, it literally works for pretty much every build and you can pivot later if you change your mind about your playstyle or whatever

Jagged SteelTier 1
Tempered SteelTier 2
Serrated FangTier 3A
bleed stacks go to 7
|
Iron WillTier 3B
parry window +2 frames

Tier 2 (Tempered Steel): you get +15% base damage and +10% Sha-Chi generation rate plus a new heavy attack chain with way better stagger, honestly this alone makes the upgrade worth it and you should rush to this as fast as possible because the damage spike is immediately noticeable and the new heavy combo just feels so much better to use

Tier 3A (Serrated Fang): bleed stack cap jumps from 5 to 7 which is kind of insane because you can stack so many bleeds on bosses, each bleed tick also deals 10% more damage and honestly this is the pick for Bleed Build and Aggressive Chi Rush, probably the best general damage option imo, the extra bleed stacks let you melt bosses way faster than you'd think and it's just super satisfying watching their health bar drain from all the bleed ticks

Tier 3B (Iron Will): parry window extends by 2 frames going from 8 to 10 which doesn't sound like much but in practice it's huge trust me, perfect parry window gets 1 extra frame too, this is the pick for Defensive Parry Master builds and honestly makes parrying so much more forgiving especially on bosses with weird attack timings, you know those attacks where you're like was that even fair, well this helps with those

Venomous Softblade

poison-infused sword with extended parry frames and honestly the best defensive sword in the game, if you love parrying this is your weapon and I've used it through like half my playthroughs because being able to parry more reliably just makes everything easier, the poison is kind of a bonus on top of the defensive kit tbh and once you get used to the extended frames you'll have a hard time going back to other swords ngl

Venomous SoftbladeTier 1
Toxic EdgeTier 2
PlaguebringerTier 3A
poison spreads on parry
|
Mirror BladeTier 3B
parry reflects projectiles

Tier 3A (Plaguebringer): successful parries apply poison to nearby enemies which is honestly amazing for crowd control in group fights and turns Venomous Softblade into an AoE debuff weapon, suddenly you're poisoning entire rooms just by parrying and I love this pick for areas with lots of adds swarming you, probably the better choice if you struggle with getting swarmed by multiple enemies and need some breathing room

Tier 3B (Mirror Blade): parrying ranged attacks reflects them back at the attacker with 150% damage and this is literally essential for certain boss fights with heavy ranged phases, like Snake Sovereign's Venom Spit becomes free damage instead of something you have to dodge, so good when it works but kind of situational otherwise, your mileage may vary depending on which bosses you're struggling with

Dual Blades Evolution

White Python & Red Viper

starter dual blades with wide arcs and fast attack speed, honestly the best weapon for Sha-Chi generation in the early game and the attack animations just feel so smooth and responsive, if you like playing fast and aggressive these are probably your best bet early on and they scale surprisingly well into the late game too which I didn't expect when I first tried them

White Python & Red ViperTier 1
Twin SerpentsTier 2
Venom FangsTier 3A
attacks apply poison
|
Storm BladesTier 3B
attack speed +15%

Tier 3A (Venom Fangs): every 5th hit applies poison DoT and this combines with Bleed Build for triple DoT stacking which is pretty gross, also increases Sha-Chi generation on poisoned enemies by 20% so your resource gain goes through the roof, kind of the more tactical choice if you like managing debuffs and watching health bars melt, it's like the death by a thousand cuts approach and honestly watching three different DoT effects ticking at once is one of the most satisfying things in the game

Tier 3B (Storm Blades): attack speed increases by 15% and your combo length extends by 2 hits, this is literally the highest sustained Sha-Chi generation weapon in the game and it's amazing for Hybrid Flex builds that rely on fast resource generation, you just never stop attacking and the Sha-Chi bar fills up like crazy, I mean you can basically spam your abilities nonstop and it feels like you're playing a completely different game at that speed

Phoenix Wing

fire-infused dual blades and every 3rd hit triggers a fire explosion which looks awesome and clears groups so fast, this is the premier AoE weapon for group encounters and I love using it in areas with lots of trash mobs because everything just explodes in this beautiful chain reaction, honestly one of the most fun weapons in the game and it makes farming feel way less tedious, you know those sections where you have to kill like 20 enemies in a row, Phoenix Wing makes those actually enjoyable instead of a chore

Phoenix WingTier 1
Blazing FeathersTier 2
Inferno DanceTier 3A
fire explosions leave burn ground
|
Phoenix RebirthTier 3B
heal 5% HP on fire proc

Tier 3A (Inferno Dance): fire explosions leave a burn zone on the ground for 5 seconds and enemies standing in it take ticking fire damage, this turns Phoenix Wing into an area denial weapon and it's excellent for controlling group fight arenas, you can basically lock down choke points and watch everything burn which is so satisfying, just drop a fire zone in a doorway and let the enemies walk through it and die, it's beautiful and also really effective for certain boss adds that spawn in waves

Tier 3B (Phoenix Rebirth): every fire explosion heals 5% of max HP which provides insane sustain for aggressive play, combine this with Blood Sigil and you can stay at full HP through most group encounters, I'm not 100% sure but this might be the best sustain option in the game for players who like to just go in and never stop attacking, you literally heal by doing damage and that's the kind of design I love in action games, lemme tell you it makes the game feel way more forgiving

Greatsword Evolution

Savage Axe

heavy-hitting greatsword with the highest single-hit damage in the game, slow as hell but when it connects things die and honestly there's nothing more satisfying than landing a fully charged heavy attack and watching a boss lose a third of its health bar, if you like seeing big numbers pop up this is your weapon, you have to be patient with the timing though and that's the tradeoff you're making with this playstyle

Savage AxeTier 1
Berserker's AxeTier 2
BloodthirstTier 3A
damage scales with missing HP
|
EarthbreakerTier 3B
heavy attacks create shockwave

Tier 3A (Bloodthirst): damage increases by up to 40% based on missing HP so at 50% HP you deal 20% more damage, this rewards aggressive low-health play and it's definitely high risk high reward, best for skilled players using Aggressive Chi Rush who don't mind living on the edge, I've died to this playstyle so many times but when it works it's incredible and you feel like an absolute monster just deleting bosses while one hit from death yourself, honestly it's the most thrilling way to play the game

Tier 3B (Earthbreaker): fully charged heavy attacks send out a shockwave that hits enemies in a line, adds much-needed range to the greatsword's kit and makes it way safer to use, better for new players who need safe damage options or anyone who just doesn't want to be right in the boss's face all the time, the shockwave also hits pretty hard and can stagger multiple enemies at once and all that

Spear Evolution

Celestial Lance

long-range spear with the tightest parry window but the highest parry reward, this is the skill-ceiling weapon and honestly if you can master the timing it's probably the strongest weapon in the game, but if you can't parry consistently you're going to have a bad time with this one ngl, I've seen people absolutely destroy bosses with this thing and I've also seen people rage quit trying to learn it so it really depends on your skill level imo

Celestial LanceTier 1
Star PiercerTier 2
Heaven's ReachTier 3A
attack range +25%
|
RetributionTier 3B
perfect parry deals 200% damage

Tier 3A (Heaven's Reach): attack range increases by 25% making it the longest melee reach in the game, allows safe poking from distance and honestly you can hit enemies before they even get close to you, best for hybrid or defensive players who like to play it safe and whittle things down from range, it's kind of the comfy choice that makes the game way less stressful and you can zone enemies out forever without taking damage

Tier 3B (Retribution): perfect parries with Celestial Lance deal 200% weapon damage as a counter-hit which is the highest parry reward in the game period, but it requires the tightest timing with a 6-frame normal parry window so you better be really good at parrying, for advanced players only and honestly I still miss the timing sometimes after like 50 hours, the damage is absolutely bonkers when you land it though and it makes boss fights go so much faster if you're consistent with your parries

General Rule: dump your first 15 Primal Shards into your primary weapon's Tier 3 and don't split them across weapons, a single Tier 3 weapon outperforms two Tier 2 weapons in pretty much every situation and you'll feel the power spike immediately, only start splitting materials once your primary is at Tier 3 and you're comfortable with it, you get the idea
