Actually this aint even just a Visual bug but also a gameplay bug ( but since i got no permission to make an other Thread i did post it here )

U did swap Searing chain lvl 1 and 2 ... It actually does 80 dmg on lvl 1 and only 60 dmg on lvl 2
and same goes for lvl 3 and lvl 4 .... i kinda doubt that it was planned like this ....
Iam playing the german Version of dota 2 and the skill description also says : dmg per sec : 80/60/120/100
So u actually deal more dmg on lvl 3 Searing chain as on lvl 4.

Please have a look into this.

Thanks in advance
