Ok, first, there is a
thread for character sheets.
Second, for power levels please test your character against the following and post the rough reports:
A Fire Giant.
A Young adult Blue Dragon (ignore the dragon's spells).
A Bebilith.
A Vrock (notice it has at-will mirror image and telekinesis to fling stuff from 880 feet away).
A pair of Mind Flayers.
An evil 10th level cleric with a big pile of 1HD human skeletons tagging along.
6 Trolls.
A lot of Shadows.
Your character need to beat at least 4 of those battles, but if you double the number of enemies and still win over half of them then your character needs to be toned down a bit.
