/**
 * Guide:
 * Lv 3 (Hard Mode) specifics:
 * - Features even more HP and damage compared to Lv 2 (Normal Mode)
 * - When players remove a buff, Beritra will spawn three "Drakenspire Pustule"
 * - There will be no helper NPC spawn
 * - When all three buffs are removed, he will change into his dragon form.
 * - As a secondary option, he can be brought down to 40% HP and will also transform into his dragon form
 * - Players will only have 11 minutes before he basically resets the fight (re-buffing & healing)
 * <br/>
 * <br/>
 * The most effective way to deal with this is to remove the three buffs ASAP and not dealing major damage,
 * avoiding starting a new phase
