Seems to work here too. I think the wounding curse uses bolts for ammo, same with the fire staff or something. That seems normal to me, as a method, you'll see that the stuff has a little bolt fixed to it. As for the graphics, they're coming up too. Fire, water walls, smoke, hell knights, and gore encrusted daemons.
I don't really like the mod as it is, it's too lethal, I lasted less than 2 seconds (literally) in a siege on a 60 man castle, where I had 40 men(NPC's, summoners,wizards,aprentices), and 27 men were killed instantly on my side. A fireball ended it all. Plus there's a bug where the second fireball you shoot with a fire staff or fire wave kills you instantly. It does feel cool though to shoot a firestaff at a troop of men and kill 20+ wizards, if you can get close enough. (I don't think you get any XP for such unscrupulous tactics).
I used blackroses method to get it going.
