editing magictype.dat

hi guys,
i need help editing the blaze graphic into firecircle graphic so that it wouldn't lag so much.
i try opening the magictype.dat using Hex Workshop. using ctrl-f, i manage to find the fire circle and copy all the data onto the line with blaze. when i start conquer, i found out that i couldn't cast my blaze at all. so where did i went wrong?
:cry:

Maybe it is casting but you arnt seeing it..

If you copied all the data in the line, you may have modified more than you need to. I'll try to help you in a sec but I'm pretty busy atm, sorry.
