The "I-Bomb" is a secondary Slot Weapon for the Demoman. The "I-Bomb" is a very tricky and powerful weapon, but it has high-risks too. The rules for the weapons are simple: The Demoman can activate the bomb and throw it against his enemies over a very small distance. The enemy must now switch the weapon to hold the bomb. The only way to get rid of the bomb is to throw it against an enemy or a helping friend. If the bomb falls on the ground or you miss the target, the bomb is going to explode while you getting hurt of it's area-damage. The "I-Bomb" has a random timer on it, so no one knows for sure when the bomb is going to explode.  The only way to see it is when the torching lure is entering the bomb and a ticking signal when it's going to explode immediately. When the bomb explodes it hurts about 65% his keeper and about 40% every person with the same color.  It's like a Tag-Chasing Game but the Demoman can control when he want's to start it. This weapon is good for facing enemy-groups alone, but if you're right with your team, it can be a huge disadvantage, because the chances will increase for the enemy to throw the bomb back your team. There is also a limit that usually two I-Bomb can be activated on one map, otherwise the random timer will become zero and the demoman will blow himself up. And besides the high risk for damaging yourself or your team, you need to replace the sticky weapons or the shield to use the bomb.
