Help me with Trickster

I use Darkness Revealed, Agitation, Bamboozle, and Iron Maiden. I've found that his ability to get quick downs makes him pretty reliable without any slowdowns. Instead, the perks help you get certain tasks done quicker so that you can find survivors and keep up with them. Additionally, I use the Fizz-Spin Soda and Caged Heart Shoes add-ons. The soda add-on helps you throw knives quicker around loops and it generally gives survivors little time to react. Generally, I'll be able to throw 2 knives in quick succession before the survivor takes a turn around a loop or object. The shoes add-on also help tremendously while ADSing around loops and loses little distance from the survivor.

Overall though, Trickster takes practice:

• Aiming down a bit helps control the recoil, but most of the time it is better not to spam knives unless the survivor really cannot escape from the flurry. This helps you both conserve knives and makes you more accurate with practice.
• The knives are quick, but try to aim where the survivors are going to go. Specifically where their backs/butts are going to be since that is generally where the hitbox is when they are running. You'll get the rhythm down with that practice.
• If a survivor begins spinning near you, but not making any distance, just m1 them. It's better to conserve knives at that point unless you are confident you can hit a majority of those knives to injure and down in that situation.
• Throw knives at survivors that you predict are going to throw down a pallet, or vault a pallet or window. Survivors are stuck in an animation when those things happen and these are the easiest times to hit knives at them. You can deal a ton of laceration during these times too with the Fizz-Spin Soda when you have your accuracy down.
• Shack isn't so bad when you have Bamboozle and learn how to throw knives through the holes in shack. However, some main buildings are rough for Trickster and I would try staying away from them if you can. Catching survivors in bad positions and areas is always the best case scenario.
• Speaking of holes, you'll find that some loops have holes or openings around them, try to use this to your advantage by predicting when survivors will go towards those parts of the loop and throw knives at them.
• Don't be afraid to m1 and do m1 killer mind games around loops. Survivors surprisingly don't expect it a lot of the time and have gotten many downs doing that.

Close-medium distance is the best time to throw knives, assuming no obstacles are in the way of your shots. Anything over about 25m away from you becomes harder to hit knives. When the survivor is at medium distance from you, it is better to throw one knife at a time (tap button instead of hold). This is because throwing a flurry will cause recoil and make it significantly harder for you to aim at that distance. It also helps to conserve knives. With practice, you'll begin hitting knives slowly at that distance.

The only times I throw a flurry of knives (holding the button) is when the survivor is out in the open at close range, when they are looping around short-wall tiles at close range, or when they are stuck in an animation, such as vaulting. At tall wall tile loops, since the survivor can easily break line of sight, it is better to be accurate with your shots. That's why I throw around 2 knives (tapping the button) around each corner where they are. This will build up their laceration and eventually injure or down them. Remember that around tall wall tile loops, put down your knives when you don't have line of sight so you can catch up to the survivor more easily, unless you are able to mindgame them and throw your knives when they least expect it through crevices in the walls or doing a backwards walking mindgame. All of this takes practice to learn.

Agitation isn't necessary. It is a personal preference on my part. I have had many times when using Agitation where I could hit other survivors with an m1 while carrying another survivor on my shoulder. Additionally, getting a survivor to a hook fast means I can go to a locker faster to reload and use Darkness Revealed to spot a survivor and begin another chase. You also don't have to worry about hook spread when using Agitation. However, again, this is just my preference. If you'd like a slowdown perk instead of Agitation, I'd recommend Deadlock or No Way Out. These perks will help you interrupt the survivor objectives.
