AnonymousWell boys and girls, the nerf was inevitable. The kings of exploration no longer reset their HP upon screen transition. But the quality of life fix so that they don't kill important enemies during parkour sections was a very welcome change, and their overall damage output combined with Pollip Pouch still make them great at shredding anything that gets too close. Still an S-tier red tool in my book

AnonymousYou already know they are gonna nerf this sooner or later, so have fun with it while you still can. This + Pollip Pouch made the difference for me with Lost Lace. Just make sure to only summon one at a time for maximum efficiency (and I suggest to try and save them for the second phase)

AnonymousOnly issue is when you have them accidentally summoned in platforming sections which requite pogoing / harpooning enemies. They kill the enemies. They make the platforming impossible because there's no longer anything to pogo / harpoon. (this caused me to die in the act 3 rising lava climb. Should be an option to remove them once you've summoned them.

AnonymousDefinitely overpowered but I don't mind this game having an option like that for people that want it. It's a decent chunk into act 2 and still uses a consumable resource after all.

AnonymousNext patch : "Fixed Cogflies incorrectly resetting their HP to full on scene change."
Still one of the best tools though.

AnonymousI'm the same dude some comments below that praised these things, I have the damage numbers when your pouch is fully upgraded. They do 11 damage per hit. With 8 uses of Cogfly available, and each Cogfly being able to do 6 hits before disappearing (assuming you do not change rooms, otherwise this number resets), 1 Cogfly does 66 damage in total, and with all the 8 uses, it's a RNG-free 528 damage in total.

AnonymousBest thing ever, but can someone tell me why 3 of them disappear when I enter a transition? It sometimes happens it's weird

AnonymousAmazing against bosses, amazing for exploration, plus they look cute. What's that? They have a high maintenance cost? Good thing they're amazing at farming because their max hit counter resets after every room transition.
It's bonkers how strong this tool is

AnonymousThese are great for short Rosary farming runs, since you can reset their hit counter at benches - this means you only have to spend Shards summoning them once, then when you respawn enemies with a Bench you're also refreshing your Cogflies. Most things will just melt to four of these guys at once so it makes farming extremely fast
and low effort.
For mid-game the best farm is First Shrine, run up to the rafters, kill the 2 big guys, then run back. Depending on whether you have flea buffs, Thief's Mark, Anklets etc. then you can be making about 90-110 rosary every 20-30 seconds. It's so efficient you would be insane not to, even if it just means turning them into Rosary Chains and Shard Bundles to use later.
Anonymousreally strong but you get it also really late, so there is that

AnonymousOkay, I haven't tried all the red tools available yet, but I can already tell you all this is probably the most broken one. Prepare for it to be nerfed.
You can spawn 4 of them at the same time. Each Cogfly can do 6 hits before they disappear. It has RNG-free damage, as it lunges onto the enemy and ignores walls and obstacles, so it's one if not the most reliable tools available. You can rest at a bench to replenish your Cogfly uses while still retaining the ones already active.
It already has ALL OF THIS.. but it also has 2 other things. Firstly, they do not despawn if you leave an area. Okay cool, whatever. But it becomes crazy once you realize that the limit of 6 hits before they disappear RESETS WHEN YOU DO SO. This is fucking bonkers. And they look cute while doing so.
AnonymousThis feels like one of the better tools out there, autonomous, homing, and will carry on after a fight if you beat something early. With good timing you can set it up so they're attacking the boss while it's doing the start of fight/phase transition scream that incapacitates Hornet. The only drawback is they cost quite a bit of shards to reload, but it's worth it.


How do the cogflies themselves take damage???
