Primary responsibility
You are main negate. If we come across a strong group with a strong healer we need your negate. Try to target healers, choke points, and objectives. Destro ultimate is for when we take enemies unaware, back door or flank. Destro ultimate is useful if enemies are really mobile, but make no mistake 99% of the time a well placed negate is what the group needs. Only ultimate when crown calls for it.

Secondary
Your rotation should look something like Inevitable Det, Haunting Curse, Blockade of storms, lightning flood, shock pulse, repeat.
Empowered Ward for increased survival and minor intellect buff.

Tertiary
Dark Conversion converts stamina to health and magicka, also applies minor prophecy to the group.
Bound Aegis is just for passives never cast.
Inner light is mainly for passives, can be used to pull someone out of stealth but only in melee range.
Pulsar applies minor mangle to enemies, you are main source of this debuff.
