Used on for the first time tonight. Wasn't sure how it works. It says it has no range penalties and requires an attack role, so I figured it must be a ranged attack against AC, like a bow, but that seems sorta weak, considering. I'm playing a wizard, and if that's the way the ring works, I suppose I should give it to someone else since with my BAB, I won't be hitting much with it.
So, is it:
1. Ranged weapon, like a bow, using BAB and Dex mod against target's AC.
2. Ranged weapon, but targets touch AC, like ray spells.
3. Or does it just deal damage based on charges without any rolls.
1 seems to be correct, although the ring is worded oddly.
Also note that if the ring hits a target that's within 30 ft, it uses its own attack bonus for the bull rush attempt.
Yeah, that's what I figured. Man, these things aren't that useful for wizards. Guess I'll give it away next session.
