I haven't put any thought into items other than the obvious.
But what about this skill build? Think it'll woyk?
1 Rain of Ice
2. Fireball
3. Deep Freeze (for the interrupt)
4. Fireball
5. Rain of Ice
6. Nothing
7. Fireball and Rain of Ice
8. Frost Nova (To set up for future use of shatter--and occasional present use, though it's not too powerful now)
9. Nothing
10. Fireball and Rain of Ice
11. Permafrost
12. Deep Freeze
13. Deep Freeze
14. Deep Freeze
15. Fire and Ice
16. Biting Chill
After this I could just max out Frost Nova and Permafrost using the last four skill points. I'm not sure how powerful these upgrades are, though. The description is vague concerning Permafrost. And I'm not sure how valuable it is to be able to stun enemy DGs for an additional 2 seconds using fully upgraded Frost Nova.
But anyway, the idea behind this build would be to do a lot of farming for exp, and when dealing with DGs, to just keep switching between fire and ice, doing two fireballs, then the chain of ice attacks (nova, rain, deep freeze) then back to fire and rinse and repeat.
Any hope for this build? And should I indeed max out Nova and Permafrost? Or should I do fire nova instead? Or circle of fire? Would the circle of fire remain after I went ice? I haven't tried that yet.
