well after some trial and error (and lots and lots of That command does not exist.) I have found out some interesting commands
.die - this actually kills the targeted enemy, instead of yourself
.lookupitem - handy for finding out the item code for a Thunderfury, or your Tier 4 set
.lookupskill - looks up a skill for you to learn, but half the time the codes are wrong >_< and you end up learning turn undead rank 2 instead of kodo riding skill
.go - the coordinates that are provided on the above website actually need to have the single int number come last, instead of first
.additem - still works as normal
now if I could only find the commands to add flying mount skill + mount (I saw it on these forums before but I couldn't find it again >_<) and add mobs/npcs
