Abilities

Call Bleak Worg
Summons 1 Bleak Worg to aid the caster in battle for 4 minutes.
Collect the called Bleak Worg before its Wavering Will slows the healer, then finish it before returning to Nandos.

Call Slavering Worg
Summons 1 Slavering Worg to aid the caster in battle for 4 minutes.
Switch damage to the called Slavering Worg while the tank keeps Nandos occupied; leaving each new worg alive increases pressure on the healer.

Call Lupine Horror
Summons 1 Lupine Horror to aid the caster in battle for 4 minutes.
Focus the called Lupine Horror before Summon Lupine Delusions adds more enemies to the fight.
Tank- Be ready to collect a fresh worg after each of Nandos's calls rather than spending every threat ability on Nandos alone.
Healer- Stay near the player collecting Nandos's summons so a called worg can be taken off you without crossing the kennel.
Damage- Break off Nandos for the worg he calls; prioritize a Lupine Horror that can create Lupine Delusions.
