... and Source Vampirism.

Hi everyone. I was hoping to get your thoughts on these skills. I've noticed that the AI seems to cheat when using them. I've experienced enemies using Blitz Attack up a tall tower I was standing on and through a iron fence (you can see though it but you can't pass though it). But when I try to use it if there's a puff of smoke or a pebble in the way or I'm not lined up perfectly straight it won't let me use it.

As for Source Vamp its supposed to be resisted with magical armor but enemies use it on me despite having magical armor and if I try to use it on enemies that don't have any magic armor left it always (and I do mean always) says blocked by magic armor. What gives? Are they just bugged or are they actually cheating? As if the game doesn't give itself a big enough advantage as it is.

Thanks everyone.
