For this build your main job is keeping up the major slayer buff for the group. To get maximum uptime (16.8 seconds) you will need to have your spell damage and max magicka as high as possible, hence the usage of bogdan (nighflame) and 3 spell damage glyphs. Be sure to proc the minor sorcery buff from your class passive from purifying light, drop your wall of elements for the damage buff from your enchant, and drink a spell power potion prior to heavy attacking. If you are still having trouble getting the full uptime you can slot in inner light on your backbar or request/use a warhorn.

It may seem counterintuitive to use RO on body and jorvuld's on backbar, but the extra magicka slot from perfected version of RO helps increase major slayer buff time. You could in theory swap them, especially if using non-perfected version of RO or if you prefer having jorvuld's on body, but you may need to do a bit of extra work to get full uptime.

For this build you will usually be assigned to kite duties except for some select situations IE ice boss on VSS.

The usage of the arcane supremacy and untamed aggression CP passives may be unnecessary as you can reach max uptime without them, but if you are still having trouble getting there go ahead and slot those in. If you don't need them use enlivening overflow and hope infusion from the healer tree.

NOTE: YOU WILL NEED TO HEAVY ATTACK TWICE (EVERY 22 SECONDS) TO BUFF ALL OF THE DAMAGE DEALERS, SO PLAN YOUR ROTATION AROUND THAT.
