Unnerf Dowan.

The previous incarnation basically made it a necessity to kill Duvessa
first, otherwise she would go berserk and easily kill the player; this
is both spoiler-ridden and unbalanced.

Instead of making Dowan run away in fear, he'll be temporarily hasted,
and receive an upgrade of spells. Fireball will replace both of his
conjurations, and Corona and Haste Other are replaced by Blink and Haste
respectively.

Fireball tracers currently don't seem to work properly, meaning that
Dowan can kill himself with his own Fireball. This is undesirable.
