1608 script

[Maerit]

If you're on a recent version of Lich, this will do ya:

if Spell[1608].known?
	loop do
		wait_until { Spell[1608].affordable? && !Effects::Buffs.active?("Beacon of Courage") }
		Spell[1608].cast
		sleep 3
	end
end

The sleep is necessary to catch the buff in you "Buffs" list in spell active, but may be longer than necessary. Also, this script would just be running in the background.
