Uhm, are you sure rend is that clear about how it works? I know in DDM they were expressly clear that was how rend worked. Indeed looking at the text of the entries I have access to, it seems much more probable that rend is a separate automatic attack that claims damage bonuses, penalties and other hindrances, such as DR, separately from the attacks that triggered it. While this IS very breakable, that certainly looks like that way it would work based on the text.By RAW, no. It is technically not an attack as there are no rolls involved for to-hit. For example, other damage modifiers, such as power attack or your weapon enhancement bonus would not apply. Nor would the damage it deals scale in line with your base weapon damage either (in the case of 2-weapon rend from PHB2). It simply tacks on a flat amount of damage when the requirements are met.
Rend damage probably should be increased if you’re Power Attacking, but by the rules, it isn’t increased. Go complain to a game designer. Don’t forget to apply that damage, though.
Yeah, he may be right about the feat based rend, though designers are not always perfect. IIRC one of them even commented on how they sometimes mix up how the rule work and even forget which rules made it into the final version they were working on. Oh, THAT Delve article was the one I recalled!I was going off this article.
Design & Development: Designing the Delve, Part 2
If a game designer answers a rules question of the top of his or her head, be a little suspicious. Those heads are crammed with previous versions, playtest versions, and Versions That Should Not Be.
Yeah. That version also seems to indicate the rend damage gets checked against DR separately. As if 2-weapon types don't already suffer enough from DR. "This extra damage is treated as the same type that your off-hand weapon deals normally for the purpose of overcoming damage reduction and other effects related to damage type"Note that 2 weapon rend has been revised in PHB2, and it now just gives a flat 1d6+1.5str damage.
A shining example of this is skip williams Rules of the Game: All About Grappling (Part Two). article, which to this day shows the rules mistake Skip Wiliams made in an article that was supposed to clarify the rules.
