[QUOTE="Mercule, post: 6868370, member: 5100"] I'm actually not a fan, at all, of 3d6 in D&D. It works in Hero because the math is already set up that way. The dials turn a bit slower, such that a +1 can be a big deal for an experienced character, but it's about the same cost to go from marginally trained (8 DC) to well trained (11 DC). The D&D math is set up to work better with linear progression. It's not really that uncommon for, say, a Fighter to have a +3 strength bonus, a +3 proficiency bonus, and a +1 magic bonus. In the standard D&D math, that's a swing of 35% chance of success. If you happen to hit the "sweet spot" on the 3d6 bell curve -- which is reasonable in a balanced adventure -- that bonus nearly doubles (+66%, back of napkin). The net result of 3d6 in D&D isn't more realism, smoother progression, or anything like that. It's increased swingyness, which almost always works against the PCs. So, I'm not opposed to 3d6 as a resolution mechanic -- I love Hero. I just don't think it fits well with D&D (or "d20") and would be extremely hesitant to play in a game that used it. If I did play, it'd almost certainly be expressly to watch the math. I wonder, if each player were given the choice between using d20 and 3d6, how many would choose each? If given the choice for each roll, I wonder how it'd evolve. [/QUOTE]
