In BG I'm not sure (never played with a Bard tbh, but I think you can read it in the manual), in DnD it can better your THAC0 and saves, sort of like a bless spell I suppose.

(more seriously it raises morale from an RP perspective, and gives boni to skils or saves form a gamist perspective)

Heh heh...you said "boni."

*Half On-Topic*

Deekin in NWN was awesome. I don't know how many times I laughed - and his BS was pretty good too.

fake edit - just noticed "BS" - meant Bard Song, but same thing I guess

*continuing half on-topic*
I think the Shield Guardian in Hordes of the Underdark was also pretty cool, pretty useful and cool looking too. Wish they would make him be summoned each time, like the elementars for example, instead of permanently dying and destroying the control amulet...
But so you'll have to watch out all the time that he doesn't die <_<

Real edit: in Baldur's Gate II you could summon that iron golem, or create your own items which would summon every creature you liked. Why didn't they allow to modify spells in NWN too like in BG2? :wallbash:
