d50 Monster Powers

Use these when you want to make monsters tougher without resorting to upping their HP, AC, or damage. These aren't the weirdest powers I can think of - I've left them relatively "standard" so they can be broadly applicable. Combine with this d50 Puzzle Monster Death Requirements table to make a d100 table.
