MAGIC ITEM IDENTIFICATION
Simple bonus items like +1 weapons, armor, etc. may be identified by simple trial and error. Anything with more complex functions or command words must be identified in the usual manner.
I hate to look at that table every time this comes up, so I’m using the variant rule from Complete Divine, page 87.
THE HIGH COST OF LIVING
I hand-wave living expenses; it’s assumed that you find enough “extra” treasure to pay for things like food and shelter. This doesn’t cover “nights on the town” or other extravagant expenditures, but it does free you to spend your gold on things your PCs can actually use.
Also, since the campaign is based in Sigil, you usually won’t have to worry about things like rations, unless you’re heading “out-of-town.”
THE HIGH COST OF DYING
Any time you would suffer level loss by being raised from the dead (via whatever method), you instead acquire a negative level until the next time you level up. This negative level cannot be removed by any other means, short of a miracle or wish. The negative level is far easier to adjudicate than actually taking a level off the character, and it’s much easier to get it back this way. This rule comes from Jonathan Drain, by way of Andy Collins and J.D. Wiker.
