Change min and max values

 

[Diazapam]

Btw, why is the - there? min="-20" max="-220"

 

[zakius]

because it uses some kind of addcreaturehealth so negative value does dmg and positive heals

 

[Diazapam]

Still think its weird but w/e, thanks for explaining

lord azteck, i have to tell you that there is far away from the frost dragon on rl tibia. it got missing attacks and very random drops. Try to figure out good interval and chance on the attacks or even try to make the other attacks if you can gl
