Cost: 6.4m elixir (because of x2 cost for spell factory (200k,400k,800k,1.6m, etc.))
New Spell: Burn Spell
Burn Spell - A spell unlocked @ Spell Factory lvl 6 which you drop on defenses to lower the DPS by a certain amount varying on the level of the spell.
(maybe add a new defense to balance it out??)
