How to beat the Treant boss in Once Human

The Treant is one tough and creepy customer in Once Human, especially if you’re playing solo. Its battle involves making the monster vulnerable by removing its vines and then attacking during the brief window this enables.

The first part of the battle requires you to attack its “Tangled Vines” to render it vulnerable. These aren’t far from the Treant itself, but are located on ledges that you need to jump to. They appear as tall, twisty columns of branches and have a pink, glowing center. They’re not far, and can be seen from the ground. One is located on the highway overpass near the tunnel entrance.

To take down the Tangled Vines you want to aim for the obvious glowing weak spot. Be warned, they will attack you, so you are not safe when doing this.

Once the vines are down, you have 120 seconds (2 minutes) to attack the monster itself. Not to sound obvious, but you’re going to aim for the glowing weak spot here as well. In this instance, it’s a woman growing out of the back of the monster. Or maybe the monster is growing out of her.

It will attack by throwing spores into the air that will slowly float toward you. They’re not too difficult to avoid, but they almost feel like a decoy for the next attack.

You’ll see the woman on the Treant glow very brightly for a very brief moment. The instant you notice this you’re going to want to run to the side and roll to dodge, as she’s about to fire a laser beam at you. This can be devastating.

Occasionally, during the battle, you will see a grey-blue fungal growth emerge from the ground. If you shoot these, they’ll create a small bubble of shield that you can take shelter in for a short while. Use moments where you can take shelter in the bubble carefully, and make sure you’re not exposed the next time you see it charge its laser.

If you can’t take down the Treant in time after destroying the Tangled Vines, the vines will regrow. You’ll need to again do a lap and take them down again before attacking the monster. You will simply need to keep repeating this until the Treant goes down for good and gives up its rewards.
