Avuro's Arsenal

I've been cooking up a chemist/inventor character and I'm going to put his stuff here. Avuro holds the skills to produce all the items here.

weapon name: Blast Daggers
description: The blast daggers are a pair of daggers with a crossguard. The daggers have a tube inside them, which spays forth an explosive compound that reacts with blood from the tip of the blade when the back of the hilt is pressed. The weapons need to be refilled every time their explosive capabilities are used since one press uses up all the explosives inside.
weapon special abilities: The weapon may be used to literally cause explosions in the wounds of the opponent. The explosive charge is small, only causing an explosion just more than the size of a head. It is, however, concentrated directly on the target. The problems of this weapon are its one shot nature and the need to pull back fast unless you want to bomb your hand.
history: Avuro made these weapons himself in a pirate ship

weapon name: Directional Bomb
description: The Directional Bomb is a tough, reinforced steel half-shell connected to a pack of explosive powder with a small hose/tube. It is held in hand and launched with a press.
weapon special abilities: The thing works by causing a directed explosion, with the small shell protecting the users hand from leftover blast. The reach of this weapon is not far, but the explosion is very violent. Anything within 2 meters of the blast weapon in the direction it is aimed is going to suffer serious injuries. The blast scatters in a sort of almost hemisphere, but te middle part of the blas travels for a slightly longer distance. A full pack of the powder is enough for about 25 uses.
history: This bomb is another thing Avuro built to augment his combat capabilities in the pirate ship.

weapon name: Airfire whip
description: This is a peculiar looking weapon. It has a solid hilt and a light, thin hose which is adorned with small blades at the end of the hose. The weapon holds a powder in the airtight hilt which lights on fire upon contact with air. The fire last only for a second or two, but is very violent in its short lifespan.
weapon special abilities: The hilt holds a pressure button which is simply activated by grasping hard. The powder is then released into the whip/hose and leaves a trail of flames in the air where it strikes. This makes the weapon dangerous even when a hit is unsuccesful.
history: This weapon was also created on the pirate ship.

weapon name: Avuro's Grenades
description: The grenades are differently coloured steel balls which burst open upon impact.
Red Line: The red line grenade has a red line drawn across it. It releases a bright flash of light.
Green Cross: The green cross grenade has a green cross drawn across it. It releases a cloud of poison gas.
Orange Circle: The orange circle has an orange circle drawn across it. It releases a powerful, small scale explosion.

weapon name: Chemistry Kit.
description: Not actually a weapon, but contains many chemicals and powder used to make these bombs and powders. Also used in conjunction with a medical kit.

As long as the character using this doesn't have a devil's fruit, these are on a reasonable level. Just remember to put how many of each grenade you are carrying on the character's sheet. Keep that number within reason.
