this only works if you have an arcane skill of maybe 10+, could work if you have it lower, but would take longer, mine arcane is lvl 17 now, and it really works good.
its that the spell whirlwind stacks. i didnt think of casting it multiple times, but you can. when you have four or more whirlwinds going on a fire drake, you see this constant stream of damage, 20,23,21,30,25,26 and so on, and the whirlwinds chase the drake, and last pretty long.
i killled a fire drake in maybe a minute or two, i didnt even have to swing my weapon once, or cast any other spell.
even better, if you are a warlock or war witch like me, all that magic damage is drained back to your health, so i was at full health after it died
im assuming you can probably whirlwind most things to death. i tried it in this room of monsters, cast the spell multiple times, they all died very fast.
so have fun
oh...and dont do what i just did, i took the dragon eggs for fun, and i think that stops them from spawning again...i put them back, but i dunno, maybe they dont come back, anyone know about this? will i get dragons again?
