/*
 * Movement for Shadow Council Enforcer is NYI
 * All visuals around Medivh are NYI (see creatures spawned around Medivh)
 * Timers at which we summon portals requires to be revisited
 * The way we summon portals may be not entirely correct and requires additional research
   Current handling is:
    1. First portal is opened when event starts (correct)
    2. When Rift Lord or Rift Keeper is defeated, next portal is spawned after 0-5s (timer seems correct)
    3. When we summon boss, we summon no more portals until boss is defeated (seems to be correct)
    4. We summon next portal even if previous was not closed. We can have maximum 5 normal portals + 1 boss portal active at once (to be verified)
    5. We summon no new portal imediately after closing any portal if we already have more than one portal active(to be verified)
