Level Damage Shared Cooldown Manacost
1 12% 36 seconds 140

Quick Gameplay Tips

  • Synergistic Combos: Always use Fatal Bonds on enemy units or creeps before dropping Rain of Chaos. Because the damage from the Infernal (Immolation/Flaming Fist) and other sources is shared, linking enemies multiplies the total damage output significantly during team fights.
  • Strategic Channeling: Upheaval is best used to zone enemies during a fight rather than trying to hit a full-duration slow. Position yourself safely behind your frontline and channel to force enemies to either walk through the massive slow or retreat entirely.
  • Infernal Micro: Treat the Infernal as a persistent threat, not just a stun tool. Use its high HP to soak up tower shots or force enemies to focus it, creating space for your team to operate while it continues to burn nearby units with Permanent Immolation.
