/**
 * Guide:
 * Lv 2 (Normal Mode) specifics:
 * - Features more HP and damage compared to Lv 1 (Easy Mode)
 * - When players remove a buff, Beritra will spawn three "Drakenspire Pustule"
 * - Helper NPCs will only spawn when the third phase begins (either by reaching the 11-minute mark or dropping below 36% HP)
 * - Helper NPCs will only remove "Everlasting Life"
 * <br/>
 * <br/>
 * Drakenspire Pustule (Poison minion):
 * - Follows a player for 20s
 * - Dies after 20s, leaving a poison skill area that deals damage and debuffs players within it
