Legacy Piece Trait Tier List — Ranked by Roll Odds

An honest trait tier list has to admit something first: below Secret rarity, the official board posts each trait as a screenshot with no numbers. Any site ranking Limitless above Warlord with a damage figure attached is making it up. What is published is the rarity band and the roll chance, and rarity in this game tracks power closely enough to rank on. The full odds table is on the traits page.

Which Secret trait is best?

They do different jobs rather than sitting on one axis. Phoenix Rebirth is the survival pick — it resurrects you outright. Astral Core is the sustained pick, shielding on every hit taken and healing on a ten-hit cycle. World Breaker trades attack speed for wide area damage, which is farm value rather than boss value. Tyrant King is the balanced defensive-lifesteal option. All six are effectively unreachable without the reroll stacks that codes hand out.

Is rerolling for a Secret trait worth it?

At 0.0067% per roll, one specific Secret trait takes about 15,000 rerolls on average, and any Secret trait takes roughly 2,500. Current codes give thousands of Trait Rerolls at once, so it is reachable — but it is a project, not an afternoon. Spend on gems and enhancement first; those are guaranteed returns.
