Locations
(Mage Asunder)

Abilities
Arcane Horrors have three types and one unique boss, and like party members has conditions for Combat Tactics:

Strategy
In a party with any one with long range attacks, it's possible to kill the horror without him even touching the party. Using long range spells like tempest or long range attacks like bows. In a party with any mage with Mana Cleanse, Mana Clash, or even Mana Drain if used in the improved drain Spell Combo can seriously reduce the effectiveness of any spell orintated monster. Especially arcane horrors.

Bug:this is the easiest boss to kill.even Leliana with a bow,can kill it.

1- all of 4 party members must stay near the door

2- send one of them,or,an animated death,or a summon wolf near arcane horror and immediately run with it to the friends

arcane horror will attack that party member with spells like paralyze,weakness or ... and a horde of undeads will follow

3- after killing the undeads,arcane horror changes his situation and you can target him from the stairs.

with a simple bow,or a magic staff,you can kill him with no danger and fight.
