Olorime,

Reflective light, snipe or Venom Arrow are replacements for Power of the Light. Depending on if we are still using vitality set. (minor buff/debuff)
Could also slot off darkflare and combo these together.

Snake in the stars set with vitality set.
Orders wrath and way of fire are alternatives for the snake in the stars.
Grace of gloom or maras balm for defensive alternative for vitality set.
Also Robes of transmutation or Armour of truth.

Medusa for pure crit, maybe orders wrath.
Gryphon Ferocity, has minor force and expedition so we can take off 2 swift enchants. a little sustain or damage. Worth? no?

Swap Bombard with Spear for group resource sustain.
Swap cleanse with recourse sustain slotted ability.

Can swap snow treaders for Trassian Stranglers.

Can swap burning spell weave on back bar for olorime for group play, also draugerkin does more damage than BSW. MIGHT be best to just go with clever alchemist though.

Some final thoughts.
Run draugerkin & clever alchemist at first. clever alchemist is craftable and should be easy to get. Clever alchemist can be swapped for burning spell weave for more uptimes but might loose tankness and damage. Swap for wretched vitality if sustain is a problem. Deadric trickery or another defensive set like grace of gloom is another option. On the front bar, Snakes in the stars punishes healing but may have uptime/opportunity issues. Shattered fate adds penetration also way of fire is an option. These are some options to swap draugerkin for.
