Tracer can only deal good damage when close to her enemies, as opposed to other Assault heroes like Soldier: 76, and she lacks durability.
After a short delay, the bomb explodes, dealing a heavy amount of damage to enemies in a small area around the bomb. Otherwise, the bomb will stick to the first solid surface it lands on. If it impacts an enemy, it will stick to that enemy. When activated, Tracer tosses her bomb forwards a short distance.
