Rapid decay + DOT from passives or gear

Hi!

Will a skill linked with rapid decay benefit from it if the source of DOT damage is from passives or gear?

say a legacy void heart, then just a random melee skill linked with rapid decay?

Thanks!!!

Yes, but Rapid Decay won't support a skill without a duration. So Earthquake, AW, fine. Cleave or something won't work.

Sorry, could you please clarify?

Do you mean that the DOT from void heart will only benefit from rapid decay if the melee skill linked has a duration tag?

Or the DOT will benefit regardless, and you only meant that rapid decay won't support the skill itself if it doesn't have duration?

XD

The latter. Rapid Decay will benefit all DoTs dealt or applied by the linked skill, it just won't support a skill at all unless it already has a duration tag (or has gained a duration through another support gem).
