This fire will last for 2-4 minutes (based on balancing).

I believe existing fire bombs burn for 2 minutes already?

I'd consider them if they were to burn infinitely, otherwise it's wasted trash

If they don't remove it and you throw a flamable resource on them, they will have twice the duration to remove both the oil and the fire (this is so you are forced to remove the oil).

Also useless. You have to 1) throw oil 2) throw flammable in a game where you can just oneshot them most of the time. Or 2 two-shot within 1 second.

Also if it goes into tool it's trash. The more I read your post, the more I'm thankful you're nowhere near crytek design board
