The idea is that, once
activated, the behemoth has a "defense system" consisting of 8 blades
which revolve around the automaton at very high speeds, sort of like a
chain saw. Anyone caught in it takes damage.
This is what it looks like so far. Feedback is appreciated:
Bladestorm Aura (weapon) aura 1; The clock work behemoth has a defense system consisting of eight jagged blades which revolve around the creature at high speeds. Anyone caught in the bladestorm aura at the start of their turn takes 10 weapon damage.
