Boom Rocket
The Boom Rocket is an item in Kid Icarus: Uprising. When used, it sits on the ground for a moment, counting down, then launches into the air. After a short time, it falls back to the ground and causes damage to anyone unfortunate enough to be in the blast radius. The time delay makes it tricky to use effectively but can be useful in crowded areas.
Description[]
The Boom Rocket is found in certain chapters as a usable item, usually in an area where it would be useful. It can also be found randomly in Together Mode, where it is slightly trickier to use against player-controlled opponents. It is best to hide the Boom Rocket in a crowded area by looking for a corner or a wall to plant it; this way, no one will see it and, when it blasts off, no one will be aware that an explosion is about to happen.
Idol Description[]
These rockets first launch skyward, after some time falling back down and unleashing a massive explosion when they land. The delayed attack makes them a bit tricky to use but effective in areas where foes are likely to gather.
