Repair Amplification

Repair Amplification increases the hit points restored by repair spells and effects. It stacks with various spellpower bonuses. It currently comes from race and item.

Stacking with spellpower
Repair amplification stacks multiplicatively with effects that increase the power of repair spells, such as metamagic feats (e.g. Maximize Spell), class enhancements that increase reconstruction spell power, item enchantments (e.g. Reconstruction), scroll mastery enhancement, etc. Incoming effect is simply multiplied by character's total repair amplification. This multiplication is applied only after rounding the amount after applying spellpower (always rounded down) and is then rounded again (always down too).

Example: Repair Light Damage on CL 5+ with 20 spellpower and 10% repair amplification should in theory restore: 1.1*1.2*(1d6+7) = 10.56-17.16 rounded to 10-17 Instead it restores: 1.2*(1d6+7) = 9.6-15.6 rounded to 9-15 -> 1.1*(9-15) = 9.9-16.5 rounded to 9-16 Note: The range is discrete with only 6 objects in each set, so the average isn't the average of minimum and maximum.

Racial bonus
Most races don't have racial bonuses to repair amplification, i.e. their racial multiplier is 1.
