I've been reading through the forums for the last month or two, and I've seen some really good advice handed out (or at the least, some very entertaining discussions
). I figure this is the place to go, since my group is starting our first Eberron adventure next weekend, which I'll be DMing, and none of us have interacted with Action Points before. I don't have the book in front of me (i'm the only one with the book atm, it's being passed around a lot as characters are being generated) but I think I'll give my questions a go without it. Please forgive anything I misquote.
Action points add 1d6 to the die roll. All fine and good. But, is this a bonus or a straight modifier to the die roll in question? In other words, on the roll of a natural 1, would the expenditure of an action point modify it up? Would it change a high roll potentially to a that of a 20, causing a critical threat? We play where a roll of a nat 20 is an autosuccess, and a 1 is an autofail
I can't see it working that way, and if I had to rule on it right now, I'd say that it's a bonus, and while it wouldn't change a "non crit threat roll" to a "crit threat", I'd probably allow for one to be spent on the roll of a natural one, to negate critical failure effects, and potenially cause success if the total value, including the roll of a 1, was high enough to suceed. It seems that even if that's not what the rules state, that it's absolutely in the spirit of what these are intended to do.
From the other persepctive, where the Action Point die is being used as an unnamed modifer to the roll, if the action die were spent on a potential crit (say, a roll of a 16 with a keen falchion), that the same value would then be added to the confimation roll, working on the assumption that this is covered under the statement that a confirmation roll is made with the same modifiers of the original roll.
So, anyone care to comment?
