The True Steel mod increases critical chance on a melee weapon by 10% per rank for a maximum of 60% at rank 5.
- The critical hit chance increase from this mod is not additive, but rather multiplicative. For example, Dual Zoren has a 25% base critical chance. Rank 5 True Steel increases this +60%, it will now have a 40% chance to critically hit. (25% × (1 + 0.6) = 40%)
- Because of this, True Steel is most effective on weapons whose critical chance is at least 20% and above.
