Vectis can be accessed after Taloc and MOTHER have been slain.

The plague of corrupted blood killed countless trolls and began one of the most terrifying periods in Zandalar's history. The constructs within Uldir studied the disease in search of a cure, but found that only isolation and extermination was effective. Unfortunately, as the facility's safeguards cracked apart, the plague was accidentally combined with a sample of G'huun's blood creating a new entity that hungered for fresh victims.



Vectis is a fight revolving around managing a set of debuffs while the boss cycles between two phases. Omega Vector Icon Omega Vector is a small DoT applied to several people at the start of the fight. Once this DoT expires, it will leave a stacking debuff that increases Nature damage taken, then will jump to the next nearest player. Managing this debuff is key to ensuring a kill.
