I have a problem with the skills which absorbs Hp. When they hit mobs they make normal damage, but against players the make x10-50 times more damage (5k-50k!). The server is interlude L2JFree..

Well we use to have a post whit a link of Fixed Skills  but now is dead , u should go l2jfree forum:

 

http://www.l2jfree.com/

 

and search for fixed skills there

 

Or u could try edit of the skill and see if it has something wrong (no seense hits normal mobs and players x10) =/
