Crossbow/Musket/Using Items on Weapons

Sorry for the three posts in one, but since Rezoner hinted at the musket as a new weapon coming up soon, I thought I would make a post regarding its mechanics:

Damage with melee attack: 1
Damage with charged attack (firing bullet): 2
Damage with special: 1.5
The special would be a bullet, which on impact explodes, dealing 1.5 damage
The charged attack would take 3 seconds
I also posted a comment with this idea, where if you were to pick up a throwing knife and you had the musket, you could press left shift to attack it to your musket. Your melee attack becomes a quick stab that deals 1.5 damage. The bayonet breaks after 3 hits
Cost: 3000 or 2750

2nd idea I had was the crossbow
Increased range and speed than bow
Damage with melee attack: 0.75
Damage with charged attack (firing bolt): 1.75
Damage with special: 2
The special would be a bolt with a rope attached, which would act like the current rope, but dealing 2 damage
The charged attack would take 2 seconds or 1.5
Cost: 2500

The third idea i had was using items on weapons
New item that has already been suggested would be added: Poison
For the bow, using a haste potion with left shift would quicken your rate of fire
For the axe, using a stamina potion with left shift would increase your damage by 0.5
For the crossbow, using the poison item would take away 0.5 health per second for 2 seconds and drain stamina
For the musket, using a grenade would fire a grenade with extra range, dealing the normal 2 damage for its charged attack
For the spear, sword, and claws, using poison also does the same thing as the crossbow
For the hammer, using a mine makes your next hit explode on impact, knocking your opponent back and dealing 2.75 damage
If they shield, they are stunned
If using the ice staff, using a mirage potion with left shift will make you fire 2 bolts at once
