Project Soul's Traits Tier List

Traits are the modifiers that turn a Project Soul’s Soul kit into a finished build. You earn trait rerolls from gameplay and from promo Codes, then spend them hunting rolls that amplify damage, sustain, mobility, or utility. This page ranks trait roles in S through C style bands, explains when to spend rerolls, and shows how traits should synergize with Souls and weapons. Like the Souls list, treat ranks as community meta that shifts with patches—especially after Reset updates change which fights matter.

Read Souls Tier List before you dump fifty rerolls into a kit you plan to abandon. Read Gems and Farming so your gem wallet and quest loops keep feeding the shop while you chase traits.

What makes a trait high value

Strong traits do at least one of the following without wrecking your kit fantasy:

• Increase consistent damage on the buttons you already press.
• Add survivability that converts into fewer wipes on Toriel, Flowey, or Dust Sans.
• Shorten downtime so farm routes print more gold per minute.
• Enable a weapon breakpoint—making a slow heavy weapon usable or a fast weapon lethal.
• Stack kindly with common Souls instead of demanding a one-in-a-million second trait.

Weak traits look flashy but rarely fire, fight your Soul’s tempo, or require gear you will not own until post-Reset.

Trait role tiers

S-tier trait roles

Universal damage amps that raise the ability you press every fight, and honest sustain that prevents death without deleting your DPS identity. S-tier also includes rare rolls that both accelerate cooldowns and preserve survivability on mid-game boards. If a trait makes Toriel and farm routes easier without a PhD in combos, it belongs here for most accounts.

A-tier trait roles

Conditional damage (bonus after dodge, bonus on first hit, bonus vs bosses) that shines when you play correctly. Mobility traits that help Flowey and Dust Sans lanes. Weapon-specific synergies that turn your upgraded shop blade into a monster. A-tier traits are excellent once you know your Soul; they are easy to misuse on day one.

B-tier trait roles

Comfort stats, minor gold or EXP helpers, and flexible utility that never feels bad but rarely feels decisive. Keep B-tier rolls while you save rerolls for S or A targets. Many B traits are perfect “good enough” stops on the road to Reset.

C-tier trait roles

Narrow gimmicks, anti-synergies with popular Souls, or traits that only work with unreleased or ultra-rare partners. Reroll these unless you are theorycrafting for fun.

Exact trait names will differ by patch; map the roll description to these roles instead of memorizing a brittle list.

When to spend trait rerolls

Spend freely when:

• Your Soul choice is stable for at least several sessions.
• You just redeemed a large code bundle (especially Reset-gated rerolls).
• A boss wipe clearly traces to missing sustain or missing damage, not to player greed.
• You swapped weapons and the old trait no longer matches attack speed or ability cadence.

Hold rerolls when:

• You are still shopping Souls every hour.
• You are one quest loop away from Reset 1 and expect gated codes to refill the bank.
• You are emotional after a wipe; tilt rerolls create expensive regrets.
• You have not upgraded weapons—traits cannot fix a starter stick forever.

A simple budget: keep a reserve of rerolls equal to one good code payout. Spend the surplus. Never hit zero before a known code drop or prestige if you can help it.

Synergy with Souls

Match adjectives to verbs:

• Aggressive determination Souls want S-tier damage or cooldown traits; sustain is secondary but welcome.
• Kindness or sustain Souls want traits that extend healing windows or add damage so fights do not last forever.
• Patience or integrity kits want traits that reward correct timing—bonus after dodge, bonus on charged hits—over flat chaos.
• Bravery or melee tempos want mobility and armor-pen style effects that keep you alive in close range.
• Perseverance grind kits want duration, DoT amp, or stamina-like traits that shine on long Dust attempts.

If a trait fights your Soul—shortening a channel you needed or rewarding planted play on a hit-and-run kit—reroll even if the trait is “S-tier” on a generic list.

Synergy with weapons and armor

Weapons dictate hit rhythm. Fast weapons love on-hit or frequent-proc traits. Slow heavies love big first-hit or ability-amp traits. Armor that already solves survival lets you greed damage traits; paper armor begs for sustain traits even if Discord says damage is king. Buy the shop breakpoint first, then reroll—see farming and getting started habits if you are broke.

Gamepasses can change starting power but should not change synergy logic. A fear or starter bundle that gives early gear still wants traits that match the Soul you actually press.

Reset-aware trait planning

Before Reset, stop at good B+ or A traits and push prestige. After Reset, redeem Reset-gated codes, then spend the new reroll pile on S-tier roles for the Soul you will use on Dust content. Do not perfectionist-reroll the night before prestige if carry-over rules are unclear—verify in the Reset UI and How to Reset notes.

Post-Reset meta often values survivability a letter higher because secret bosses punish glass. Be willing to swap an S damage roll for an A sustain roll when Ruins Dust Sans ends your run.

Practical reroll session

1. Confirm Soul and weapon for the week.
2. Redeem codes; count rerolls.
3. Write one target role (example: “sustain for Flowey”).
4. Roll until you hit S or A for that role or hit your reserve floor.
5. Test on a real boss, not only on Whimsun.
6. Log results; adjust target role if deaths were mechanical, not statistical.
