My gear is extra shield, dmg reduction and shield recharge per second. Why? S&a is a bug target but none can crit while your shield is on so keep it that way.
Her sneaky skills can let you escape if needed or hunt a fleeing target and slow it. A good combo is fetch then slow.
Always use fetch in close-mid range, bullets destry him and you dont want to miss that over shield, dont limit your strategy to that, help galth with pulls or assasins with stuns, meele characters should be scared of you specially rath, phoebe and attikus, you can pull them out of their ult.
At lvl 5 alt ernate your skills to have your shield full and soak more dmg.
When you cant engage throw boomerangs, if you are being pushed hard avoid risky situations and boomerangs, if you see a los health target risk and divie in cloaked finish your job, get some extra shield and get out.
If they are fleeing and fetch or cloak are in cd you could try boomerang
It’s a slightly cheesey tactic, but later on she has a mutation that increases the boomerang damage, which actually ends up having a better DPS than her melee attack, due to its faster attack. So if you can aim the boomerangs right, they do more damage than just straight melee sadly. I always played them as an attacker. Building for attack speed, movement speed, and attack damage, but that’s just my preference. Sneaking around behind enemies and trying to split them up. Pulling weaker or lower hp players off to murder them silently.
