You may get a message stating, "The hands of darkness prevent you from proceeding," after being checked to enter the battle. Originally thought to be held back due to a campaign battle, but entry was allowed shortly after still during the battle.
Attacks with a dagger. Deals ~50 damage against average defense.
Seems to have fairly high accuracy.
Every minute, he will use a random Dark ArtsStratagem. These Stratagems do not wear off when he casts a spell, and last for the minute until he uses another one.
His Stratagems are stronger versions of players' Stratagems. Alacrity will make his spells instant cast, Manifestation will make all of his spells Area of Effect, and Ebullience will significantly boost his elemental and healing spells.
Is immune to Silence and builds resistance to Sleep quickly(first Sleep II may stick without Elemental Seal, however subsequent attempts at sleeping will more than likely require ES). Other status effects, including Stun, seem to have a normal chance for landing.
Seems to be resistant to Repose, WHM could not land with capped Divine Magic despite two attempts.
Fairly succeptible to Head Butt as long as it's not spammed, repeated use will make him resist the stun, but if you lay off for a short while, the resistance seems to recede.
At 50% HP, he will use Tabula Rasa. While under its effect, his Stratagems do not wear off, allowing him to cast spells under the simultaneous effect of all of his Stratagems.
His storm spells decrease the damage done by Elemental Magic of the same element. For example, Thunderstorm decreases damage done by Thunder based spells.
At around 15% HP, he gives up and the battle ends.
