In the desolate, twisted landscape of 2026's Once Human, survivors face horrors from beyond the veil and challenges from within. Among the myriad tasks that fill a player's log, some whisper of fiery power—Incendiary Blasts. The game, ever the cryptic companion, doesn't hand you the recipe for this particular brand of destruction on a silver platter. It's a puzzle to be solved, a secret to be uncovered while you're busy just trying to stay alive out there. But for those in the know, mastering this fiery technique isn't just about checking off a box; it's about claiming valuable rewards and adding a spectacular tool to your survival arsenal.

🔥 What in the World is an Incendiary Blast?
Don't let the fancy name fool you. An Incendiary Blast isn't some high-level superpower reserved for the elite. Nope, it's actually one of the more straightforward mechanics a beginner can wrap their head around. In simple terms, it's all about using weapons or throwables that deal direct fire damage to take down your targets. As of the current season, the tried-and-true method for pulling this off is with a trusty Molotov Cocktail. While promotional material has teased the existence of flamethrowers, the community is still waiting to see if those glorious streams of fire will officially count toward these challenges. For now, the humble bottle of fire is your best friend.
🌳 The Classic Challenge: Tangled Vines and the Treant
One of the most common places you'll encounter this challenge is during Season 1's Treant boss encounter. A specific phase asks players to "eliminate a Tangled Vine with an Incendiary Blast." Here's the lowdown on how to ace it:
-
Find the Fight: Locate and engage the Treant boss in its arena.
-
Spot the Target: During the fight, three pulsating roots, the Tangled Vines, will be present.
-
The Strategy: Your goal is to kill one of these vines using fire. A single Molotov might not pack enough punch for the final blow, so here's a pro tip: soften it up first! Use your primary weapon to whittle down the vine's health, then finish it off with a well-aimed Molotov. Talk about adding insult to injury!
Here's the best part: you don't even have to defeat the Treant itself to complete the challenge. Once that vine goes up in smoke and you hear the satisfying ping of challenge completion, you can choose to disengage. A word to the wise, though: if you are fighting lower-level bosses on Normal mode, think twice before using precious Controller items. Sometimes, the cost outweighs the reward.
🧪 Getting Your Hands on Fire
So, where do you get these bottles of boom? They're not exactly rare.
-
Looting: Standard Molotov Cocktails are scattered throughout the open world, waiting in containers for a savvy scavenger. You'll likely accumulate a decent stockpile without even trying.
-
Crafting (The Upgrade): The real game-changer is unlocking the Explosive Throwables memetic node. Once you have this knowledge, you can head to your base and craft Improved Molotov Cocktails at a Synthesis Bench. These bad boys do more damage than their standard counterparts, and you can churn them out as long as you have the materials.
