Efficacy

Type: Prefix
Effect: Efficacy refers to clicky/potion effect that provide a temporary bonus in the damage (and healing) of all spells. The bonus is 10% per tier and lasts 1 minute. I-IX number written on it indicates maximum spell level affected.
Notes: Efficacy and Potency items work as "Universal" spell damage amplification and will work on spells with unusual damage types. However, Efficacy comes in the form of a duration limited buff, while Potency lasts as long as the item is worn. Unlike other temporal spell boost effects, Efficacy has no advantage over Potency at the same spell level and magnitude.
