Most of the stalker gear has accuracy and power, some with crit, surge on the helmet is an exception.

Use the tank companion, gear him up as you level. Maul on proc, discharge on cooldown, 2x thrash + shock. Use sap on non droids and disable the companions aoe. Builds and rotations in the sticky, for deception.

lvl 50 Deception - Xalek - Run around when he does the storm and avoid it, use a combination of jolt/low slash/Overload to interrupt him when you can, if you miss an interrupt, get xalek out of the aoe by making him passive briefly. Didn't need health pots, just used a presence stim. If you use the three skills i mentioned to stop his casts it's easy.

I play assassin, I spam the "auto attack" key whilst waiting for force, it's basically a filler key to press in-between actual skills, it might as well just be an auto attack, it does nothing significant besides 3 white damage hits. This isn't engaging, it's just annoyingly pointless, the break in combat makes the actions feel less fluid, automation in this case is favourable, briefly smashing that key in-between attacks is ball aching, literally my balls start to ache, and I've recently had them checked.
