This is also how you prevent the +5 bonus on Charms in a Hostile Situation. You move in while invisible, then Silent Charm Monster. Since he wasn't aware of your presence, he's not recognizing you as being hostile. Sure, you show up, but by that time, he's already your best friend, and who wouldn't want their best friend to show up?
Yeah, this is the only reason I'm really interested in Silent Spell. It is so
up this character's alley...
Plus, my allies would not mind this at all
... especially the Rogue. Greater or regular, do you think? If I get Greater (4th level spells: Solid Fog , Enervation , Black Tentacles , Charm Monster ; I'm thinking EBT), I can replace Invisibility on my 2nd level spell list with Mirror Image, which is nice. Considering Invisibility was coming at level 9 anyway... just getting Greater seems to make sense.
