Pursuer Z3 and Sniper Exo. Pursuer Z3 provides X-RAY and Sniper Exo gives Wall Break. Probably good at duels.
I suggest putting on the Portalius set, so that you don't get damage decrease when you use the wall break weapon, in this case the Portalium Rifle. Otherwise, your loadout seems good to me.
You can use Pursuer for boosting damage so your snier exo is 1 shot, but I heard Pursuer is kinda bad
What do you think?
