I was looking at Book of the Dead[2] description, an it says there's a 10% chance of causing Coma on the enemy but, at Server script (item_db.txt):
{ bonus bMatkRate,15; bonus bStr,3; bonus bInt,3; bonus bLuk,-20; bonus2 bWeaponComaRace,RC_DemiHuman,100; bonus bAspdRate,getrefine(); if(BaseJob == Job_Sage) bonus3 bAutoSpell,662,1,10; },{},{}

I tested myself and that's 1% chance, not 10%...who's wrong? Description or Script?
