This boss is mostly a hard hitter boss but has a few highly irritating things to be aware of.
It is best to avoid getting to 4 hits on him as he will counter you if you continuously attack him. Knock him until he falls on the ground, and then back away INSTEAD of stomping him. If you stomp on him he seems to be much more likely to counter by jumping in the air and body-slaming you. This attack is highly frustrating as it cannot be blocked and has ridiculous tracking (I've seen him literally change directions in the air before). The attack also does a great job at predicting where you will be and has a big hitbox so it's very helpful to avoid dealing with it as much as possible by creating distance instead of stomping once he falls over.
At phase 2 he will get mad and slam the ground. You can avoid getting knocked over from the shockwave by jumping, but be aware that debris will fall immediately after it. Don't stand in the shadows, which alert where it will fall. First small debris will fall followed by 2 large ones that unlike the small ones, won't go away.
Abobo will attempt to pick them up and throw them at you. You can however pick them up first and throw them at him. If he does manage to pick one up though, you can make him drop it (and break it) by attacking him.
In his third and final phase he will have a new ability that sucks you in to him. If he succeeds he will hit you for a good chunk of your health. To avoid this, run to the outer map but beware of more falling rocks. Additionally, he can now stomp the ground more than once at a time, and he has a new move that sends out fire on the ground. The fire will return to him after hitting a wall so be aware of that.
I hope this is enough info for you to beat up this big meanie.
