Does Convalescence effect heals received from others?

[Fynlar]

GLA/PLD doesn't even actually get Cure innately unless it's subbed, so if we're talking innately learned abilities only, Convalescence would be entirely useless for the class that learns it >_>

So yes, it works for all received curing magic.

I do think the description could be made clearer though, because I remember having a similar question myself when I first picked up this ability (specifically, I was wondering whether it boosted the cures I received, or the cures I casted). Stating "curing magic received", similar to what XI did, rather than "for self" would make it simpler to understand imo, along with making it clearer that it also applies to magic cast on you by others.

There are conflicting reports about whether it affects "Second Wind". Personally, whenever I tested it on my Marauder back in the day, I never noticed any difference.

It doesn't. Just tested it, healed 375 without Convalescence, 381 with. Obviously that's just random variance and not a 30% difference

Pretty sure it's strictly for magic, like the description says.

Yes it does increase heals from other (curing magic). My wife is my personal healer and it increases heals by 30%. I tested this a while ago. It will not work for bloodbath and the like since they are not "magic"

Jesus christ, it's been tested so many times. People used to think it worked on our self heals... guess what, it doesn't.

I guess this depends on what you mean by 'self-heals'. I would consider casting Cure on yourself to be a self-heal, which is absolutely, positively affected by Convalescence.

Convalescence affects any Healing magic cast upon you.
As a PLD, this includes your own "Cure I"s as well as most healing spells cast on you by someone else (both players and NPCs)

It does NOT affect Bloodbath or Mercy Stroke...Inner Beast/Storm's Path/Thrill of Battle. There are conflicting reports about whether it affects "Second Wind". Personally, whenever I tested it on my Marauder back in the day, I never noticed any difference.

This is correct. I don't know if it has been changed since then, but I personally tested it with Second Wind right after PS3 release and did not see any difference.
