I was wondering if people thought it was a good idea to try to compile some short and un-obvious tips & tricks in the game into a stickied thread. The AUDACITY of someone with less than 10 posts suggesting such a thing. But hey, I finally won yesterday so I'm feeling good!

-You can hold a dagger (or mindstar?) in the offhand when armed with a sling
-Rogue/Shadowblade/Marauder classes Deadly Strike is an instantaneous attack! (edit: schooled by nate, Cursed Slam is not instantaneous!)
-Cursed class Blindside can go through walls!
-Learning Dream Walk is awesome teleport escape route for antimagic
-Shadowblade class Shadowstrike gives automatic ranged crit to level 4/5 Illuminate!
-Escort talents can be given to golems
-You get three allocatable stat points whenever you have an out of body experience (Slave compound, dreams - maybe this one's a bit spoiler-y?)
-Don't forget most (if not all?) undead bosses are unable to heal
What else ya got?
