And I quote:
This creature is worth 25,000 GP—the teeth are made of diamonds and if carefully and time-consumingly taken out are worth 30,000 gold pieces (but only 5,000 gold pieces if hastily pulled).
Oh, and rereading the original text it clearly says the "softening" affects magical bonuses to AC:
Every time it hits, its opponent goes down one Armor Class (so +2 armor becomes +1, or a Wyvern with Armor Cass 3 goes to 4).
I guess we'd better change the Special Ability with "
Note that this penalty affects any enhancement bonus the target's armor or natural armor might have first, then affects the target's mundane AC bonuses. If this negates all the magic armor's enhancement bonus the armor loses any special abilities it may be enchanted with, such as Arrow Catching, for the duration of the softening."
