Level 93 Penance Mark Chieftain^3.23

Notes

80% shock and an additional 20% avoidance is recommended for the storm shroud setup.  You can use an abyss jewel instead to cover the missing 20%.
Chaos res above 50% overall is recommended, you can go lower if you need to cut corners however be wary in the forest around purple camps.

cold iron point weapon swap is used to keep spires alive after applying a small ignite then swapping.  defiled forces will keep the ignite going forever.
if you get stuck in the mobs open a portal and exit to character, remember to swap back to the main before re-entering.
you can use the kiaras to also attempt to free yourself by gving you control of your character by becoming stun immune.

you can pick up more warlock notables but realistically sanguimancy and penance are all you will need, take more purple wisps afterwards

spam penance mark at tough rare and unique monsters (or annoint +1 curse)
