I'm wanting to use Spectral hand for buff spells (Resist Energy Communal for example) and want to make sure I'm not violating some tenet I'm not aware of.
There are two valid reasons I could see to prevent this:
Can the hand travel that far?
The range for the spell is 100 +10/lvl, so as long as the hand doesn't travel more than that distance total, it should be able to move to everyone. One might argue that it could travel twice that amount, as it can travel that far and back at max range.
Can I have the hand touch multiple creatures?
The Hand touches count as attacks, even though I'm touching allies, so I am limited to touches equal to my iterative attacks.
A forgiving GM might let it go through, but those are the limitations I can think of. Thoughts?
