This block appears as a vis relay supported by four black poles. It can only be placed on an arcane workbench. It acts as a normal vis relay but also recharges a wand or scepter placed in its workbench.
Naturally, the recharge rate is limited by the aspects and strength of the relay or energized node powering it. Regardless of the power source, each charge relay can only accept 5 CV per aspect (that is, 1 point of each aspect per second).
On either side of the middle row, place Greatwood rods. On either side of the bottom row, place iron ingots. On the top middle slot, place a vis relay.
