Warder Stilgiss

Lower Shadowforge City
The lower circuit connects Incendius at the Black Anvil with the Hall of Crafting ramps and Black Vault balcony. Clear a section of Fineous's patrol before intercepting him. Finish Stilgiss and Verek before handling the coffers, and leave the final relic coffer closed until the group is ready for the vault guardians.

Warder Stilgiss
Elite HumanoidVerekElite DemonStilgiss can root the party while Verek uses extra attacks against a victim weakened by Curse of Blood.
Abilities

Frost Nova
Inflicts Frost damage to nearby enemies, immobilizing them for up to 8 seconds.
Keep ranged players away from Stilgiss so Frost Nova does not immobilize the whole group.

Frostbolt
Inflicts Frost damage to an enemy and reduces its movement speed for 4 seconds.
Interrupt Stilgiss's Frostbolt while controlling Verek.

Frost Armor
Account for Frost Armor slowing melee attackers instead of chasing Stilgiss through more enemies.

Frost Ward
Surrounds the caster with a shield that lasts 1 minute. and can absorb a fixed amount of Frost damage.
Use non-Frost damage while Stilgiss's Frost Ward is active.

Curse of Blood
Remove Verek's Curse of Blood before his Physical attacks exploit the increased damage taken.

Thrash
Gives the caster 2 extra attacks.
Prepare for Verek's extra attacks, especially if Curse of Blood remains on the tank.
Tank- Establish threat on Verek before Frost Nova can pin you in place. Keep him off the healer while a damage dealer covers Stilgiss's Frostbolt.
Healer- Prioritize Curse of Blood removal if you can remove curses, or call for it. Verek's Thrash can turn that increased Physical damage into a sudden tank-health drop.
Damage- Focus Verek while maintaining an interrupt on Stilgiss, then finish the caster. Frost attackers should change schools during Frost Ward rather than spending attacks into its absorption.
