wouldn't chilling aura or crystallize rune be better?
no, it wouldn't
130% damage is like a small tickle vs barbs
Obviously, but it still works quite nice if you use Cold Blooded and high raw dmg build with enough ehp to be able to stand still while casting Diamond Skin - Crystal Shell + RoF - Snow Blast / Cold Blood. This skill is quite nice against low dmg melee oponents (just like Storm Armor - Reactive Armor works nice against low dmg ranged oponents ex. tank dh's).
Anyway test it and let us know what you think about it. I see no point in talking about things you didn't use / test / etc. (but maybe that's just me?).
I actually tested this quickly with hola last week, when mokkal said it was the most balanced with hota.
It is nice, but a wash over storm armour so it doesnt have me sold, probably need more testing though. U actually loose more dps than i though removing sa in trade for better survivability but the nicest part is the free freeze u get when he hits u, but the chance is lowish id say around 15% and the chill just overlaps with rof anyways.
as for the runes i tried:
jagged ice was a nono coz its damage is pathetic vs barbs, unlike vs monks coz it also seems undodgable, so it trades very badly as hota still hurts a ton so u wont be wanting to get hit, if u want the dps just stick to storm armour.
cristalize seemed the better option as at least the dps tradeoff was for a good mitigation buff the bad part is that u dont get the full benefit till the third hit so ur pretty low on health already.
