Lower the attack as a skill?

[Nirvana22 0]

Well on my server I have a problem with the ability "Dispel", the bug is in that takes a lot of critics (max 21k), could help me lose the critics as the most of 8k?

 

Query:

INSERT INTO `skill_proto` VALUES ('66', 'ÆĹý¼ú', '3', '1', '1', '0', 'HP', '-(40 +5*lv + 2*iq+(10*iq + 7*mwep + number(50,100) )*ar*k)', '30+120*k', '', '', '12', '-(40 +5*lv + 2*iq+(10*iq + 7*mwep + number(50,100) )*ar*k)', '', 'ATTACK,COMPUTE_MAGIC_DAMAGE,SPLASH,REMOVE_GOOD_AFFECT', '', 'NONE', '10+40*k', '7+23*k', '', '', '', '', '30+120*k', '0', '0', 'NORMAL', '5', '0.6', '1800', '200');
