Utilizing the [Shield Of Shadows] augment and [Health Conversion] provides 98.35% damage reduction. When combined with [Umbral Vitality] and Arcane Blessing, your Effective Health Points (EHP) will [Reach] 130,517. Additionally, summoning allies serves as effective distractions. If you desire more range, consider adding an extra forma and equipping [Overextended] over [Stretch]. The increased range benefits desecrate your summons range( they have to be within a certain range to provide you the 90% DR) while the added strength enhances your summons. This setup has proven effective in general Steel Path missions, offering remarkable survivability even against level 1250 enemies. Feel free to customize the arcanes based on your preferences; for a summon-focused build, replace Arcane Blessing with Theorem Contagion. If you have a decent kitgun, consider incorporating it into your loadout. I use two yellow shards for casting speed and a purple shard for the [Equilibrium] effect. Aura is also flexible i just haven't figured out what i want to put there yet.
