first of all, thanks for the reply.
a few things. first of all, i had envisioned any character-created effects being maximized or empowered, not item-created. but i didn't clarify. so i will do that.Aspect of the End Times: How can I say... This is scary. Really, really scary. Maybe you should tone down the extra crit range and multiplier. I mean, do you really want one of these guys using UMD on a Staff of Transmutation and firing a x4 damage Disintegrate? (160d6 damage )
second, how would an empowered or maximized disentigrate do 160d6 damage? even at 20th level, it would be max 60d6 (empower), or an even 240 damage (maximize), unless i have been missing some component of the game for the last few years (which is certainly possible...). the only thing i can think of is that you are thinking that a character with the appropriate meta- feat could empower an already empowered spell, etc (but that would still be less than 160d6). is that it? that is something that i will clarify as well.
and lastly, the crit multiplier for physical attacks: i don't see this as too high. so far it is the only one that i specified correctly from the beginning that it doesn't stack with similar effects, and a pair of uber critical modifiers on physical weapons doesn't strike me as too powerful for an 8th-level effect, especially for the binders that are generally kind of weak anyway. the only way that i could see this being abused is with some super-flurrying or two-weapon, infinite attack sequence. i am sure that there are more ways than those, but my brain works slow.
so, i am editing those now. thank you for the inight. i would never catch stuff like this without your input.
