It’s time for more 4th edition fun. This time its for the Shaman…Spirit Ectoplasm
Feat: You and your allies can now flank with your spirit companion. Your spirit companion now provides cover from all attacks that cross your spirit’s space.
A quick and dirty feat. While the spirit companion is a beast, the fact it can’t flank hurts some people. Thoughts?

I like this one. I always felt disappointed when the bear couldn’t flank. It’s a big scary bear! It should be distracting to an enemy, ectoplasmic or not! Also, I think having Slimer as a spirit companion should be an option.
if wizards can have a at-will utility power for there fimilar to flank, then there should be a feat or utiilty for the shaman’s spirit companion.
I think I know where the inspiration for this one came from.
“Oh right, I forgot they can’t flank. In that case it shows up here and possesses the hexblade making him attack with +2 hit and +3 damage bonuses.”
One thing I’d do would be to make the cover partial for a first feat since ectoplasm is kinda liquidy and easy to pass things through, but have a separate one with this as a prereq that makes it fully corporeal.
I don’t know how far down the road people would want to go for that one. If I did do that, I would end up making the full cover feat have some other benefit. Ideas ideas…
