Planning a build and just wanted to see if anyone has any suggestions/obvious mistakes I've made in this planned POB for it.

General idea: use stampede to avoid movement speed penalties from cyclone and brass dome (extra anoint is also nice), use cyclone cast while channelling VD with spell cascade for damage and ignites, eye of innocence should then cause me to take damage setting off desecrate/unearth CWDT and allowing me to gain endurance/frenzy charges with charging offensive, use storm brand with archdemon crown 4 link for exposure (35% with mastermind of discord), power charge generation, combustion for even more fire resistance reduction and ignite prolif for as many ignites as possible. Ngamahu's sign should counter the self damage from Eye of Innocence. Martyr of Innocence is just a lot of damage.

I think I need 22 (528 to trigger / 25 damage per ignite) ignites per trigger (350 ms) to get optimal amounts of damage so any advice for skills with lots of hits per trigger here?

I should have 9 from VD balls (3 per cast X 3 for each spell cascade) 9 from VD corpse explosions (or are these merged into 1 explosion? or 3 explosions?) and then I was hoping that storm brand +cyclone + whatever random skill was suggested (leaning towards ball lightning although if there's something better please tell me) to get the remaining ignites needed to trigger optimally.

I should end up taking no extra damage from crits, with 3 endurance/frenzy/power charges, a fair amount of armour from Brass Dome and I should have Primal Aegis to make up for the life pool being a little low (I really hope aegis skills don't stop you from triggering CWDT).

Any obviously incorrect/questionable things I've mentioned/suggestions for improvements? (Other than the missing rares for life/resistances/attributes).

I stole the archdemon stuff from Uberdan's Fire Burst character, and the charge generation self damage thing from Jousis if you want to check out their builds.
