Here are four builds that collectively super power each other and cover each other’s weaknesses. They are each intended to provide significant team support in different and complementary ways, while also being playable as solo characters. Each build is a caster with a channelled attack that has a high crit damage (Obliterate, Flames of Ignaffar, Seal of Blight). This allowed me to focus on only two stats across the builds to significantly boost the overall team damage: OA and Crit Damage. The support from these builds comes in a variety of forms: Massive enemy debuff, massive team damage boost, incredible healing, and damage mitigation. It’s worth noting that even having just one, two or three of these builds in your team can provide significant boost to your team’s chances of success in high end SR. At a later date I’ll post a summary of the collective team benefits and debuffs to enemies. For now, enjoy these four builds. They’re a lot of fun!! 
Click on the “> Click here for Full Details” to see the full write up for each build. The details described for each build are when playing solo, and does not describe each character while benefiting from the buffs of others. For example, Warcaster’s Flames of Ignaffar has a crit damage of 175%. This is not including the +35% crit boost from The Fury Witch and other crit damage boosters.
From left to right in the image above, we have:

- Focused Gaze: 18% Reduction to Enemy’s Physical Damage
- Nullification
Side Note:
Using a low level Familiar with low pet resistances, you would think that this pet would disappear instantly in most fights. However, it doesn’t. Because you’re a ranged character with high damage, it’s rare that you are surrounded, and even in that instance, it’s uncommon that the Raven is right next to you if that happens. It does die from time to time, but I find it weirdly uncommon to be without the pet. Often by the time it dies, it is off cooldown and available to recast.
Weaknesses:
- 3 MIs. These do NOT need specific prefix/suffixes, but the ones chosen are mainly to bolster out resistance overcaps for solo play.
- Limited forms of healing - This build relies on Raven, Blood of Dreeg and Vampire Fangs
- Low physical resistance (24%) and armor (1400). High damage absorption % helps to balance this.
