If you are going to build a Wizard/Rogue and plan on finding/disabling traps, make sure your saves are high enough that if you stand where the trap is going to spawn you will not be 1-shotted........on normal..........REPEATEDLY. Take the rez outside of the trapped area, is that a difficult notion to grasp???
Also, while using your "uber casting ability", please make sure you can either a) handle the aggro yourself or b) make sure the rest of your party is nearby so we can dispose of said aggro'd mobs. You spam-casting acid arrow on them will not kill 15+ mobs chasing you at the same time when you are bumping around the quest with 110 hp and 0 Fort.
Do not run in the opposite direction with a train of aggro following you like a Mardi Gras parade.
/rant off.....you know who you are, that is all.
