Dark Souls: Remastered · Weapon upgrade path
Chaos upgrade
Chaos upgrades reinforce weapons from +0 to +5, add Fire Damage, and scale with Humanity rather than physical stats.
How it works
The source says Chaos adds Fire Damage and scales with Humanity, with no physical stat scaling. It describes the path as recommended for low-level players with low stats. The stats source separately says Chaos weapon bonus damage from Humanity scaling is capped at 10 Humanity.
