In Challenge Mode there is an extra phase added to the fight. The first and second phases are similar to that of normal mode but Vindicta hits much harder and her life points are increased to 300,000. Her increased damage makes it impractical to use Soul Split even during the first unmounted part of the fight. Gorvek's dragonfire attack will also hit much harder, doing around 1500 per tick and can quickly kill a player if they do not move away quickly enough. Vindicta will mount Gorvek upon reaching half (150,000) LP and Gorvek's ranged attack can hit as high as 6000+, so it is highly recommended to use Protect/Deflect Ranged to mitigate the damage, especially when coupled with Devotion, Debilitate, or Resonance.
