what do you use, one two or all three??? (I MEANT< FIRE, SHOCK, ICE) (SORRY)

what are the pros and cons??

Shock.

One of the high level Destruction perks lets you disintegrate people with shock spells. It's awesome.

I use lightning, because my character class is a "Storm Sorcerer". I never use frost or fire, even though they have more useful effects; I am limiting my self for roleplaying reasons.

I went with fire in the end, because I liked the way fireball explodes, its awesome.

Frost seems like the more practical choice to me though, higher level perks give you a chance to paralyze enemies with it, plus it just slows them down in general.

Shock seems interesting but I never did find the equivalent adept spell for it anywhere so I didn't consider it.

Chain lightning is the fireball equivalent, it chains to multiple targets near impact.

my mage took every single perks on the destruction tree.

pros: its fun to switch between 3 elements from time to time.

cons: less perks to spend on something else

Lightning and Ice. Lightning for throughput and Ice for crowd control/slows.

Lightning is ideal.

-It deals lots of damage
-It instantly kills things at 15-20% health
-Ranged nukes are instant with no travel time.
-Chain lightning stagger locks can CC an entire room
-Thunderbolt makes you feel like Zeus himself.

Chain lightning? Aw hell. How come I missed this?

Sounds awesome. Oh well, Maybe I'll stick a few levels worth of perks in lightning too later on.
