In the Heroes Battlegrounds context, defeating The Prototype can give you a small chance to obtain Warp Portal. If you don’t get it, your pity increases by 3, which improves your odds next time; when the left-side notification number drops below your pity, you get Warp Portal.

How it works

  • Beat The Prototype boss.
  • You have a chance to receive Warp Portal.
  • If it doesn’t drop, pity goes up by 3.
  • Keep farming until the notification number is lower than your pity value.

Practical tip

If you’re asking about the boss fight itself, the available result I found is a gameplay guide for a different game context, not a reliable source for a general “Prototype” encounter. For this specific boss reward question, the drop is the important part: Warp Portal is the reward tied to defeating The Prototype.

Quick note

If you meant a different game or a different “Prototype,” tell me which one and I can narrow it down.
