The Only In-Depth Jessie Guide You'll Need

BUILD EXPLANATIONGadget:
Players, especially lower trophy players, underrate Spark Plug soooooo much. Recoil Spring is good until like, 500 trophies, when players start to develop brain cells. Beyond that, players can just dodge / walk away / avoid the turret when it’s gadgeted. Also, her turret is used for area control, and Recoil Spring can’t really do that.Spark Plug is SOO much better because it allows the turret’s shots to actually hit (unless they’re like Max or Crow or something). While Recoil Spring can provide more damage, most players can just run away without dying. You can’t really run away while slowed down that much from Spark Plug on the other hand. Also slows are just really useful in Brawl Stars in general - even if your turret gets instantly deleted, you STILL get so much value if you manage to use your gadget. Star Power:
Shocky’s bounces most of the time just won’t hit because of how slow they are. Even if they do, only like one or two will hit, which is like 500-1400 damage max, which isn’t terribly a lot. Just want to say, Energize synergizes INCREDIBLY well with Spark Plug - Energize offers not only more turret survivability, but also if you catch multiple brawlers with your gadget, you can easily just shoot at your turret and the bounces will hit all the brawlers caught in your slow gadget.Gears:
+1 Gear: Let’s face it, Jessie turret is pretty trash without her gadgets. Every time you use your super, you always want to gadget - in EVERY gamemode. When I run out of gadgets, I just feel like the turret provides so little value. To me, +1 is a must.Damage: Her main attack doesn’t do the most damage, so damage gear is always helpful. She can do around 2450 with damage gear, and ~2900 with Hypercharge and Damage gear, which is a lot.Shield: Jessie is squishy at 6000 HP, and squishy brawlers always benefit from Shield Gear.Pet Gear: Does more damage to the Heist Safe.Of course, go Speed Gear / Vision Gear if you want on bushy maps. HOW TO PLAY HER:
Jessie has a decently long range, so you kinda want to adapt a pseudo-sharpshooter gameplay style until you get your super. (However, unlike sharpshooters, you can rush brawlers with less than 6340 HP and win a lot of the times, because she has a way faster unload speed than most snipers. She’s still squishy though, so mind that.)
She has wide shots, so it can be easy to hit them. However, try to avoid auto-aiming. Her shots are slow, and enemies can easily dodge auto-aims.
She also has bouncing shots, so make sure to take advantage of enemies sticking together. If an enemy is low, but is camping behind their teammate who just respawned with an invincibility shield, you can bounce her shots off the invincible teammate to kill the low-hp enemy.So what happens when you get her super?
When you get her super, you can either place it in valuable chokepoints to provide area control, or you can save her super so you can kill enemies. I mainly do the latter, but I will place her turret for area control in Hot Zone and sometimes in Brawl BallIf you want to provide area control, make sure to place the turret behind a wall. If it’s out in the open, anyone can safely just burst down your turret from a distance. Once they get near your turret, slow gadget, and spam them. If the enemy is a high dps brawler, you might want to shoot at your turret for that extra survivability, but other than that, try to aim towards the enemy.Jessie is also just as good, if not better, at defeating enemies with her turret. In fact, most higher level players consider Jessie as a tank counter because of 1v1 damage she can output. In fact, with her hypercharge, you can beat nearly every brawler in the game if you play it right. (Speaking of her hypercharge, her hypercharge kinda carries Jessie. It gives the turret way more HP, as well as way more damage. Also she has an INCREDIBLY fast hypercharge rate, at only around 10~11 hits, which takes no time if your bouncing shots hit.) When going aggro with the turret, you don’t need to worry about placing it behind walls. Try to throw your turret in a place where the gadget can catch a brawler in its range, maybe even two brawlers if they lack high burst damage. Try to avoid throwing your turret into three brawlers, because the turret can get easily deleted. Also, you should only really throw your turret at two enemies if you have hypercharge - or else the turret might still get deleted.Once your turret is down, gadget immediately (slow gadget) so that the enemy(ies) can’t escape. If they are squishy, spam shots at them - if they have normal HP or are tanky, spam your shots at your turret so it stays alive longer.How do I counter assassins / tanks?For assassins. If you don’t have super or hypercharge, you might be able to win if you have a teammate besides you, but if you’re alone, give up. 95% of the time, you’re gonna lose.
If you have super, you have a chance of winning. When they jump you, just immediately super and gadget, and mash auto-aim. Even if you die, hopefully your turret will finish them off.
If you have just your hypercharge, if you keep your distance, and they’re squishy enough, you maybe can 3 tap them.
If you have your hypercharge and super, you can win the slight majority of the time. Just hypercharge super and gadget immediately, and start spamming auto-aim. This method almost always works against Edgar. For tanks, you out range them. Just keep your distance, when they’re like half health, super + gadget, and you should be able to finish them off. Tanks aren’t hard to win against for Jessie - after all, she is a tank counter.That’s all folks, have fun with Jessie!
