If you're still grinding away in 99 Nights in the Forest, you've probably already heard the buzz about the Frog Invasion patch. Yeah, the one that dropped back in 2025, but honestly? It's still the talk of the Roblox town in 2026. The big star of that update is the Poison Master class, and players are absolutely losing it over this toxic new playstyle. No joke—it flips the script completely, letting you drench enemies in venom and watch them melt while you kick back. Talk about a satisfying power trip.

Now, before you can start spreading disease and decay like a pro, you've gotta unlock the class. And in true Roblox fashion, nothing comes for free. The Poison Master costs a cool 200 Diamonds to grab. No other hoops to jump through—just diamonds. So, if you’ve been collecting them like a magpie, you’re already halfway there. But if your wallet’s lookin' a little empty, don’t sweat it. You can either swipe your way to victory by buying Diamonds at the Currency Shop with Robux, or you can roll up your sleeves and grind it out the old-school way.

Here’s the lowdown on how to farm those shiny gems without spending a dime:

Method Estimated Diamonds Notes
Boss Hunting 10–30 per boss Some bosses respawn quickly; team up for faster kills.
Daily Quests 15 per quest Resets every 24 hours; super reliable.
Golden Chests 5–20 per chest Spawn randomly across the map; keep an eye out.
Badge Rewards (one-time) 50 per badge Easy pickings for new players; grab ’em while you can.

It might take a hot minute to stack up 200, but if you’re fresh to the game, those badge rewards are a total breeze—free Diamonds just for playing. Veterans, on the other hand, might need to grind a bit harder, but hey, that’s half the fun, right?

Once you’ve got the bling, head straight to the Daily Class Shop in the game’s lobby. A couple of clicks and bam—the Poison Master is all yours. And let me tell you, the starting equipment already feels like a breath of fresh air compared to the vanilla classes. You get a basic venom-infused attack that stacks poison on enemies, which is a solid “chef’s kiss” right out of the gate. But the real kicker? Leveling up the class.

Yep, every class in 99 Nights in the Forest can be leveled up, and the Poison Master is no exception. The catch is that each level requires you to grind out specific challenges while actually playing as the class. Think of it like a rite of passage—kill X number of poisoned enemies, survive Y waves without taking damage, that kind of jazz. The tasks aren’t rocket science, but they do keep you on your toes. And the payoff? Three killer Perks that turn you into an absolute nightmare.

The table below breaks down every level-up and the Perk you unlock. Trust me, it’s worth the sweat:

Level Requirement (simplified) Unlocked Perk Effect
1 Kill 50 enemies with poison damage Toxic Trails Dashing leaves a trail of poison puddles that damage anything that steps in them.
2 Survive 10 boss encounters without dying Corrosive Touch Your basic attacks reduce enemy defense by 20% for 5 seconds.
3 Poison 200 enemies (assists count!) Plague Bearer When a poisoned enemy dies, it explodes in a cloud of venom, infecting nearby foes.

Leveling up might look like a grind on paper, but in reality, it’s a walk in the park compared to scraping together those initial 200 Diamonds. Most players report knocking out the first two levels in just a few solid sessions. And once you hit that final Perk—Plague Bearer—it’s game over for any mob dumb enough to group up. The chain reactions are straight-up beautiful, turning every fight into a fireworks show of toxic green.

Despite all the drama Roblox faces these days with lawsuits and whatnot, titles like 99 Nights in the Forest keep cranking out content that feels genuinely fun. The Frog Invasion patch didn’t just add a new class; it added a whole new vibe. So if you’ve been snoozing on the Poison Master, do yourself a favor and unlock it. Your enemies will hate you, but your damage numbers will speak for themselves. Now get out there and make that forest a lot more dangerous—one poison puddle at a time.
