Plenary indulgency

Hi guys i need to clarify this skill changes.
Sorry if its posted i tried searching it but couldnt find it.

Grants Confession to self and nearby party members.

Upon receiving HP recovery via Medica, Medica II, Cure III, or Afflatus Rapture cast by self, Confession triggers an additional healing effect.
Cure Potency: 200
Duration: 10s

So what it does is that for 10 seconds my heals will do an aditional 200 heal when using the attached spells?

Yes they get a 200 potency heal added. Its very useful for when you know alot of damage is incoming.

It's exactly like that. You could almost think of it as like Fey Blessing, except you pre-cast it instead of post-cast it, and it goes off in less than 5 seconds (because you don't need to wait on Eos/Selene), and it doesn't require a particular fairy up or cost fairy gauge.
