Hellish Hand Granade
This massive grenade does ~85 damage, minimum, and includes 128 sticky flames at 2 damage each and 128 normal fire at 2-6 damage each.
This can be used as a very large grenade, as most of the normal grenade's tactics work here, it also helps if the hogs get trapped in the fire, as this spells almost instant death. However, they may survive if they are blown out of the way (Check the wind to see which way the fire will float).
The Hellish Hand Grenade has a fixed 5 second timer, and does not have modifiable bounce.
