My friend taught me this great spell, it's dangerous, but it's strong! It's called dragon slave, i think it should be on this site.
the words are:
Darkness beyond twilight
Crimson beyond blood that flows
Buried in the flow of time
In thy great name, I pledge myself to darkness
Let all the fools who stand in our way be destroyed
by the power you and I possess...
it calls fourth the powers of dragons!
