A metal-built container that can only be built inside of a house, and should be relatively expensive (i.e think sawmill in terms of cost/bulk)
1. Has a reasonable built-in storage (Cupboard sized, please.)
2. Has a boiling pot built into it, that supports a 6x6 space, and upwards of 100l of water built into it. Counts as a boiling cauldron if lit.
3. Counts as a live fire when lit
4. Has a slot for utensils (mostly just a Pan right now) that, when used, treats the wielder as if they have said utensil in hand - think Alchemist's table.
That's all, would just be nice QoL for cooking stuff.
