it was more like a set amount of mp per lvl on a tick basis at a rate of maybe twice ur body regen tick, also when it took damage off other players it didnt just take that amount off ur bar, it took ALOT less damage than the hit, could have a dc 50 warr caining it indefinately at lvl 3 and it would never die unless u could 1 hit it for my max hp.
the damage it did was based on the mc of the caster, but it was never very much, full amc taos would just be flinching, normal warrs would take maybe 20 damage per hit off my clone with mc 20-50.
pretty sure ive mentioned this before but nothing was done except to make them use FD. i suspect clone is the way it is to ofset the damage reduction in mc-pain ratio and also the greatly reduced damage of FF and the whole standing around after casting thing.
just my 2 pence
