Efficacy Support
Supports any skill that deals damage or has a duration.
What does Efficacy Support do?
Efficacy Support can support a skill that deals damage or has a duration. PoExplorer currently matches it with 39 published PoE 1 skills after applying the source-declared compatibility rules.
How to think about it
A broad duration-and-damage option. Confirm that the active skill actually has a duration or damage component before comparing it with a narrower support.
What it can support
PoExplorer accepts a match only when this support's allowed types intersect the active skill's source types, none of its exclusions conflict, and any gem-only restriction is satisfied.
