I guess only a couple doubts remain now: can I use a self-limited Smite with Additional Recipients to enhance multiple weapons on the PC? For example enhancing a ranged weapon and a sidearm together in case he finds himself in melee later on.
And again about Additional Recipients (more in general now): does the caster need to maintain a power on all the recipients or can he terminate it selectively (keeping the power active on some recipients but not on others)?
Anyway, I'm moving away a little from my original idea, going for a sorcerer archer instead (between the other characters I've seen, melee should be decently covered already 🙂). The idea in a nutshell is that of a half-orc raised by a lone wizard, who after a hard period after losing his guardian decided to get back out there, become an adventurer and possibly follow the wizard's footsteps (so basically planning to multiclass Wizard at some point and take Bonded Object for the +1 to Spellcasting).
