Quick Question about Bountiful Sunlight

If two people used Bountiful Sunlight right next to each other (say, a host and his summon), would they benefit from both of the HP regen buffs? Or is the spell not allowed to stack like that? If it did, this would be awesome for the 2 v 2 arena.

EDIT: Bah, nevermind. I just stumbled upon a thread about it on another website. It doesn't stack, sadly. Which also happened to include not being able to stack with Replenishment. Oh well. This thread can be deleted / locked I suppose.

Never tried it, but I honestly do not see that working that way.

Well, since it's only a personal buff, it can technically stack, unless the game specifically prevents that. 20 HP a second would be awesome. I haven't tried it though.

me thinks not, my dad runs a lvl 55 princess guard character and ran into another PG once and used the spell at the same time on the host, no precipitous increase hp regen was noted by me or dad, host was at half hp when the spells were used.

Ah, ok. Would anyone be willing to test it (PS3)? I haven't seen actual confirmation of it anywhere, such as on the wiki. I've got a PG build at 50 that can be leveled up to the 100 area easily.
