You either need to bait them or pressure them. You can bait them by sliding round a corner then immediately jumping and Icarus dashing backwards or blinking away. That’s assuming they are camping round the corner waiting for you. Transversive steps with the longer slide helps or if your blinking try Astrocyte verse. To pressure them throw a axion bolt near them and start shooting. Preferably you don’t want to be in line of sight when throwing your grenade, but you want to be there shooting when it hits. In which case Ophidian Aspect with the quicker weapon ready speed will help. Basically your trying to get them to either waist their shot altogether or miss a few bolts.
