Festival of the Moons

Exile target undead. Gain life equal to target's
total casting cost.
Overload {{2}{w}{w}}: Exile all undead. Gain life
equal to the total casting cost of all exiled targets.
Every temple of Neithur will send out priests, whom
parade about the city calling out to the dead to join
with and accompany the procession back to Neithur's
embrace.
