I came up with this idea while in the shower.
how about a sword that starts out at 3* and does normal damage, hmm, i am thinking a fun chaotic charge, maybe a small AOE swing that inflicts a random status effect, yeah, that sounds nice, now 4*,hmm hmm hmmm, how about shadow damage and a charge that sends out a purple blade of dark energy, yeah, that also sounds great, oooh and maybe on the 2nd swing you could inflict curse, wait a sec, that seems a bit unfair,i know, you have a chance to inflict curse on yourself too, 5* time it seems, maybe just a beefed up version of the 4*, a bigger blade charge, higher damage, sounds about right.

name time

3* Imprisoned Blade
4*Dissatisfied scholar
5* Dissatisfied ScholarXXL

Well i hope nobody came up with this idea first, would love to get some feedback :)
