Universal Draconic Slots

Use Host Forge to upgrade a target armor, tool, bow, crossbow, or weapon. The target remains the original item; the forge stores the module host and OP state as upgrade data on that stack.

The five input positions are:

• Center: target item
• Top: tech core, which selects or raises the host tier
• Left: width material; each item adds one grid column
• Right: height material; each item adds one grid row
• Bottom: matching OP/energy core, which enables or raises the OP interface

The three tiers use the following materials:

On the first upgrade, the tech core and matching energy core are required and are consumed. The same rule applies when raising the tech tier. The supplied tech and energy cores must match; a lower tier cannot downgrade an existing host. Width and height materials are consumed according to the number of grid slots added, up to the configured tier limit. A forge operation with no new core or grid expansion is rejected.
