The 1000 Degree knife

Spy melee

This weapon is different from other knifes since, this sets nearby players on fire when you backstab a enemy and giving him a speed boost, making him able to run away and still deal damage to other enemies that have noticed him, but the drawbacks to this weapon is that you only remove 75% of your victims max health on back stab, making you trade for a knife that can take advantage of the enemy that you have stabbed. Also making it so you can run away from the other enemies that have spotted you, and if they are within that radius you burn them too making them retreat instead of trying to find you. Also you remove 75% of your enemies current health, not 75% of their max health. Also the knife grants you a passive 20% damage resistance when you have this equipped making it easier to fight pyros, so this removes the dopamine power of instant kill backstabs, for a role that makes everyone panic instead of trying to make yourself panic by having the enemy team try to find you.

Tips:

You can use this to shut down sentry nest that have a pyro next to it since, the fire resistance will make you last much more longer.

Use this knife when a bunch of enemies are packed together since, this only shines when the enemies are close to each other since you can burn
