There are still a lot of references to gold, instead of coin (some of them, like "gold and glory" might be intended).
- Carouse and Supply mention gold.
- Bard, Fighter, and Thief have gold mentioned in their gear.
- There's that "what's gold" section in chapter 2.
The bard's It Goes To Eleven mentions music. Not sure how that fits with converting Arcane Music to Arcane Art.
Page 160, the sidebar quote has a typo "likfe" instead of "life".
Got some things from the change log that don't appear to be in the 2.1 document...
End of Session still says "defeat".
None of the cleric damage spells say "ignores armor", except Harm, which only mentions that the damage you take ignores armor.
The wizard's magic missile does not ignore armor. Not sure if it's supposed to.
...unless I got an old version of the document, but it does say 2.1 and has a lot of the other changes mentioned.
