Wondrous item, common
As per this magic item this bombchu is the mouse-like device which has been constructed of thin, glistening metal and also packed with the explosive powder. Such as one is just over the 1 foot long, it almost 1 foot wide, and of course it is about 3 or 4 inches tall. So one weighs almost 10 pounds.
Being an action, you can easily activate this beautiful device by casually setting it down on to the ground, but at which point that it would race forward in a direction of your choice, within a zig-zagging but straight line at a high speed. This hums with the loud and distinct sound as it is travel. Of course it travels 100 feet in this direction on a particular turn that you activate it, and of course an additional 100 feet within this direction at a start of each of your turns if it hasn’t yet exploded.
During it is traveling autonomously, the bombchu has an AC of 18. It normally travels over up any of the wall, over ceilings, or else through any kind of difficult terrain without it is to slowing down. But whenever if this bombchu enter into the water, then it continues to travel along the button of the reservoir unimpeded.
However the traveling bombchu would explode upon entering a creature’s space, taking damage, or else at an end of the third turn after you have been activated it. Whenever it explodes, all the creatures almost within 5 feet of it must be making a DC 13 Dexterity saving throw.
But if you’re proficient with your bombs, and also add your proficiency bonus to this specific DC. On a failed save, then a target would suffer 14 (4d6) thunder damage from the forceful explosion. Al though the damage a bombchu inflicts to the different objects and also the structures has been doubled.
Even though, you can make the ranged weapon attack with the bombchu by throwing it, like it was identical to a Hyrulean bomb.
