MM Glossary
cf: p282 "minion" -- This suggests the term "standard" should be defined in the glossary, maybe something like:
Standard: A standard monster counts as one monster of its level for encounter building and rewards.
Silvered Missiles
PHB p 220
Silvering arrows gives you a full quiver. Silvering stones gives you a full pouch. Silvering bolts gives you half a case.
Perhaps that "10" should be a "20"?
