Well I've not been able to post for a while *sighs*, but that has led me to draw up some early lessons for us to learn.
Gina's dungeoneering tips:
No.1: Never use unidentified magic items.
No.2: It's probably not a good idea to enter a dungeon when most of your party are badly injured, and they are all out of spells.
No.3: Funky mushrooms are bad.
No.4: Funky (unidentified) potions could also be bad.
No.5: Never let your drow priestess go off for a bit of moonlit nookie when people are injured.
Feel free to add to the list!
