Keywords are:  'deathmarch march'

A deathmarch is when a god takes a group of players to difficult mobs
and tanks for the group.  Typically, the god will only take melee
damage - which means that the rest of the group must survive incidental
attacks and area effect attacks.  It's also the group's responsibility
to kill the mob - the god will do no damage.

Deathmarches are typically run as events.
