How about for leveling you try a different skill build?
Ice Bolt level 3
Ice wall level 5
Ice blast level 15
Subzero Shield level 0
Gust level 10
Snow Rolling Level 5
Frost Pillar level 5
Run around and try to gather up as many monsters as you can. Next, use frost pillar so they are pulled into it. Quickly use ice wall on the enemies. Use ice blast 3 times in a row while the enemies are still being pulled in with frost pillar and the ice wall is still there.
If the enemies had only a little bit of hp left after ice blast, just use ice pike + gust on them a bunch of times.
Alternatively, you can use snow rolling if you feel like it, but if the enemies don’t die after snow rolling ends, they will be thrown everywhere and it might take time to mob them up again.
Freeze enemy + Ice blast or Freeze enemy + gust will be your best mob killers. Also, you need to get the gust attribute (it’s called collision damage) to let you hit unfrozen enemies too.
I recommend you go to klaipeda ch1 and find a buff shop and purchase all of the buffs (they should be around 700 silver each, and each buff lasts about one hour). They will add a lot of damage to your skills and will help you with leveling. You might even be one-shotting the mobs with these buffs.
Also, if you can, get a hold of a weapon called “Five Hammer” (check the market) and put 5 red gems (five stars) into it. It should increase your damage by a lot. This is the weapon people use for leveling, and it will get you all the way to 315 if need be. And you can even reuse it for your alt characters.
