If you are looking for a good WT4 or KT4 build, I would recommend:

Fire
Frost
Gale
Clock
Lightning

Use clock for mobs, switch out for Lightning on bosses. Gale is tricky, however this build gets you through the tombs much faster, with added risk because there is no shield to save you.

I also find staffs to work better in these tombs, however that might be because of my play style.
