Changes most of the Arcane Horrors' spells, with new visual and gameplay effects.

 Install using DAI Mod Manager.

 No conflicts that I'm aware of.

 Full list of changes:

• Exhaustion Field: A modified version of Pull of the Abyss that deals Spirit damage and drains your mana/stamina while pulling you in. An AoE that applies Slowed appears as a warning.
  
  
• Freezing Bursts: Ice bursts cascade towards the target, inflicting Cold damage and inflicting Frozen (v2).
  Four ice glyphs appear in more or less random locations that detonate to deal Cold damage and inflicts Frozen (old version).
  
• Lightning Bolt: A bolt of lightning strikes and paralyzes one character, dealing Electric damage, while knocking down nearby characters.
  
  
• Fade Step: Replaces their teleport with Fade Step. Mostly a quality of life change, so your party doesn't "forget" about targeting the Arcane Horror like they do when they teleport.
  

 You may also be interested in my Revised creature immunities mod, if you don't like the Arcane Horror being immune to most status effects, and my Enemy spells reworked mod, which has a file that makes Freeze and Paralyze durations last longer.

Updates: 06/09/2017: Uploaded a new version (v2) with some minor changes.
