Spellbinder Glyphs will now Freeze or Paralyze you, instead of knocking you down, depending on their element (Fire Glyphs still just knock you down). The Mage enemy's Fade Step esque Escape ability will now also Paralyze or Freeze you depending on element (I haven't found an Ice Mage type enemy to test it on, though, and not sure one exists in the game), though this seems rather hard to proc.

 Install using DAI Mod Manager, same as any other .daimod file. No conflicts that I'm aware of.

 Updates:

• 30/07/2017: Added a file that modifies Corypheus' spells. His beams now Paralyze you, his red lyrium bursts and Fade Step ability now Freeze you, and his meteors now Panic you. If you combine this with my Heartbreaker difficulty mod, his summoned Shades can trigger Shatter and Discharge combos on you. Largely obsolete now that I've made a newer mod that modifies Corypheus' spells more extensively, but it's still there if you want
• 06/08/2017: Added an optional file that increases the default Freeze/Paralyze duration from 2 to 6 seconds to make being Frozen/Paralyzed by enemies more punishing.
• 06/08/2017: Added another file that adds the Fear status effect to the attacks of Terrors and Fear Demons.
• 09/08/2017: Added a file that replaces the Pride Demon's Guard ability with a blast that interrupts you and kills your barriers.
  

Known bugs:

• The Pride Demon spell purge file causes the game to crash when approaching the summoning circle in Solas' quest (but not after the cutscene). I imagine it might cause some problems in the prologue, too, so best to install it after the prologue and uninstall when doing Solas' quest.
