A 4.5lb Bag consisting of an infinite amount of brass, this brass can only be used in magical tinkering, you can have up to 5 separate devices active at once (i.e. Brass lantern, Brass Pickaxe) and you can spend two of those charges to create any set of artisans tools. If you make more than the allotted amount of devices at once, everything disappears, reappearing in the bag, you can free a charge by putting a device back in the bag, or if the device's health reaches zero, or returning via command spoken out loud (doing so will destroy any custom components used in the device). It takes 10 minutes of concentration to create one device.
You can also create tiny constructs which can then be enhanced by the chart below.
Enhancements-
Walker- 1 charge
The construct gains a walking speed of 10ft and increases Dex checks by +1 (stackable)
Crawler- 2 charge
The construct gains 10ft of walking speed and 10ft of crawling speed and increases Dex checks and saving throws by +1 (stackable)
Flyer- 4 charge
The construct gains a flight speed of 30 ft and increases Dex Checks and saving throws by +3
Reinforce- 2 charge
The construct gains 2 max HP and gains a resistance of your choice. Also increases con and strength checks and saving throws by 2.
Trigger (remote)- 1 charge
Trigger/control another enhancement using your reaction. You can activate this whenever by using your reaction.
Trigger (event)- 3 charge
Trigger another enhancement when a certain event to your specification happens, this also doubles the effect of the triggered enhancement.
Detonate- 1 charge
The construct explodes, voiding any components used in the machines making, causing 1d4 Force damage per max hit point of the construct (x4 damage on terrain, structures, or constructs). This can only be activated via the constructs health reaching zero, or the trigger enhancement.
Detonate (special)- 3 charge & an explosive component (coal, gunpowder, sulfur)
The construct explodes, voiding any components used in the machines making, causing 1d8 Force damage per max hit point of the construct (x8 damage on terrain, structures, or constructs). This can only be activated via the constructs health reaching zero, or the trigger enhancement.
Caster- 2 charge
The construct can cast a single cantrip that you choose whenever you choose this enhancement at the same stats you would normally cast at. If in combat, it will automatically attack the enemy you are attacking to the best of its abilities, if impossible, it will attack the nearest perceived enemy. You can change this by using the trigger enhancement, which allows you to take control of what it does on its turn by using your reaction.
Record- 2 charge & a glossy/transparent component (a silver coin, a shard of glass)
The construct will telepathically show you a live feed of what it can see.
Interact- 1 charge
The construct can "interact" in any way you mean it to, it can take any action besides the attack action, (i.e. dash, help, grapple) and can also interact with other objects (i.e. stir a potion, hold a light)
Slash- 1 charge
The construct can attack anything within 5ft with a +2 to hit and 1d4+2 slashing damage
Custom- 1-6 charge & a component
Use a special component to create a special enhancement that fits the theme of the component, the DM (or bred since he made this mechanic) can decide how much charge it would require and if it is feasible to even do so.
