Sight Unseen (Priority Mission) Boss Guide

This will be one of the few times that you get to battle Taskmaster again.

Most of Taskmaster's attacks focus on powerful, leaping hits that makes him move around the stage often. Whenever things get tough for him, he summons a set of Watchdogs - a Hellhound, a Shockmutt, and a Skydog. Deal with them first before returning your attention to Taskmaster.

The main strategy here is to stay away and use ranged attacks. It is highly advisable to use Iron Man or Black Widow here to quickly land in attacks from range.

Watch the ground for red markers to know if Taskmaster will execute his leaping radial attack. If the red marks stay, that means he set a bomb there that will activate if you get too close.

It is possible to push your opponents outside of the rooftop for an instant kill. But be warned as this can happen to your allies as well.
