Fire upgrade
Fire upgrades reinforce weapons from +0 to +10, add Fire Damage, and remove all stat-scaling bonuses.
How it works
The source says Fire adds Fire Damage and removes all stat-scaling bonuses. It describes the path as recommended for low-level players with low stats, without giving a comparative damage measure. The stated reinforcement range is +0 to +10.
Read the supporting references
A source-bounded reference to eleven weapon upgrade paths and related stat-scaling effects in Dark Souls: Remastered. It describes reported functions, scaling changes, upgrade limits, and a few stated restrictions. It does not compare effectiveness or verify current balance. Guidance explains the referenced mechanics; it is not a tested damage ranking. Check the stated edition and source version before applying a patch-specific detail.
