/*
 * Greater Poison Cleansing Totem has no passive spell (nothing found in sniffs). What spell should it use?
 * Seer Olum's event is NYI (should be handled in DB)
 * Damage of fathom pets is too low, core issue (if creature is summoned by spell, damage is quite low)
 * Bestial Wrath cannot be applied on Fathom Lurker and only applies on Fathom Sporebat. The reason is Creature Type Mask = 0x00000001 (BEAST).
   It is unclear if this is an issue or not
 * Sharkkis should be able to summon multiple pets, at this moment he can have only one summoned pet per time
 * Transform spells (handled in SAI for each totem) for totems cannot be casted by totems because of Totem::IsImmunedToSpellEffect (SPELL_AURA_TRANSFORM)
 * Timers requires to be revisited
