Glad we're settled on the armor.
I prefer option 1 for the melee weapons.
Character class advancement sounds right.
Updating Reave Working Draft.
I think these are between CR 2 and 3. Their damage output plus special abilities makes them strictly better than bugbears, but I am not convinced they're quite as powerful as ogres. I guess I'd lean toward a weak CR 3, but what do you think?
Definitely a "strong CR 2". In general I'm against giving a monster a CR higher than its HD unless it has really dangerous special attacks and the Reave doesn't. I wouldn't rate them as nastier than a Leopard, which is my go-to for the high end of CR 2.
Their slow movement speed is a severe hindrance and their astral fading ability isn't that valuable in combat use since it requires full-round actions to fade in-or-out of existence which rather ruins the element of surprise, although at least the Reaves are incorporeal while they're doing so so they might escape receiving a sword in the guts before they're solid.
Hmm… I'd seriously consider tweaking the Astral Fading so it's more useful. We could change the action(s) to a less time consuming standard/move/swift action so the Reave can do something useful during the full round it shifts planes, like drinking a potion or moving to a more advantageous position.
