To the Korax developers: several months ago, while first exploring the Korax mod, I posted a few comments about weapons strength, etc.; particularly the frost shards. Well, with more time to become accustomed to your mods, I retract those "complaints". After noticing that those shards eventually use no mana I found you can use a "machine gun" approach with them, effectively blanketing an area. Some have complained about your opponents being frozen in place briefly, and often (usually) in your way, but I found it a simple matter to switch to a wand, any wand, for one shot, then back to the shards. Also noticed that one hit from the shards will immediately stop those "Creature From the Black Lagoon" rejects wallowing in the slime.
But why can't you freeze Heresiarchs or Korax? The shards will damage them,and (if you're in "fag" mode) eventually kill them; but they don't freeze. I assume no graphics option for a frozen Heresiarch?
