/*
 * Combat timers requires to be revisited
 * Singularity may be much trickier:
    1. Check if singularity should change targets
    2. Check if despawn timer depends on how much targets singularity hits by passive spells
 * Check if Dark Fiend should change target
 * Berserk for Entropius should be triggered from Entropius' AI since M'uru originally despawns after summoning Entropius,
    NYI, currently triggered from M'uru's AI
