ARK Official PVE: The Island - Solo all 3 Island Alpha Bosses with 1 Deino

Rex armies are a thing of the past! One Deino, 3 Alpha kills. Including Dragon!

Step 1: Get a good fully imprinted Deinonychus (1.3k Stamina, at least 15k HP) with 80+ Saddle.

Step 2: Go to the 3 Alpha Arenas and try to always stay under the Boss to minimize damage. Staying at the feet of the Dragon will prevent his fire reaching you. Wear some good Riot/Flak gear for Dimorphodons.

Step 3: Profit! All Island Tek Engrams are yours.

Tribemate was there for fun; soloing will actually make it easier, because aggro will stay on you and the boss will jump less around. With enough skill you can do all 3 Island Bosses in one go, without the need for a little healing in between. Everything should take 15-20min including preparations.
