/*
 * Timers requires to be revisited
 * SAY_INTRO is NYI, Zul'jin should say it when player opens Malacrass' door
 * Berserk requires additional research. Is it really used?
 * SPELL_ENERGY_STORM doesn't get removed on phase end
 * Damage of spell 43150 doesn't increase
 * SPELL_OVERPOWER should be used after the target dodges (?)
