For me too "multi-charactering" is the way I go

I like to start with a Ranger/Mage who also make use of melee fighting here and there (if necessary or just for fun!) ...
Question @GabeN :
can you give me some more information about "how" to make "Explosive Arrows" better? (which skills or stats are important?)
I personal find "Ranger Stealth" a nice skill (for a Ranger), also for a Mage when you use frequently "ranged" spells like Firebal, Magic Missiles, Magic Blast ...
(drawing a Bow and have Ranger Stealth ... it's great using "ranged" attacks and/or spells! )
