glitch ? (HEALING/KILLING)

ok so i have been trying to figure this out for some time, i have 2 clerics on my server that can friendly pk

let me explain stream of rejuvenation normally heals players, but for them it drains the hp to 0, and heals a little bit, now i have been trying to figure this out, i have my own cleric, same weps, same hex, same lvl skill, i use it it works fine, i have them take off everything but the gm wep is still drains hp to 0, they heal with any other wep that does not have 9999999 for the magic att or phy att, and it works they heal only, i tried to just make a new wep, they bought a wep out of an npc and it worked right, so i thought must be the gm magic sword, wrong, i then increased the stats of that gleave that moments ago worked correctly, stats changed to 9999999 for only mag and phy att, leaving all other stats alone, and once again 0, i have even taken the hex code of the skill itsself and compaired it, same as to mine that works, any sujestions?

LOL

You give GM Wep to your players and wonder why they can heal-kill?!

This is no glitch that is just a stupid admin and mathematics...

It's called INT-Overflow they have an heal that is > 33k or > 2.4b depending on the gs used value...

So suggestions:
1) max lvl 105 max 150
2) no GM Weps to players
3) No senseless stzatt editing like +5000 INT Stones
