The best perks that you could use for Slim are, Quick switch, Health regen, and Reload speed. With Q.s. you can switch to your healing drone, leech gun, and spore clouds a lot quicker. H.r. is useful when you’re using a cloak, it’s also good when facing Wraiths and Krakens, and when you’re on the chase with little wildlife to shoot since the assault would take it all out… Reload speed is still a viable perk to also run with since it helps reload your leech and spore cloud gun faster.
Find that comfortable sensitivity where you’re able to track and shoot the monster with your reticle of course. My sensitivity is at 69.
Fight within a spore cloud as it’ll trouble the monsters ability to smell and it’ll also help you and your teams dodging potential. Grassy areas and behind trees or obstacles that you could circle would help avoid detection or focus.
Healing drone works well while doing splits, if someone were to get hit by a dune beetle, and you were nowhere near, you could still heal them; Unless they got pounced. Also during combat when against a monster that changes targets.
I hope that all of this information would help get you comfortable, if you were to play as Slim.
