an addon mod that adds an "entity free" version of the summon stations that ask the relevant charm to be inserted into blocks inventory
for example ,if u wanna have 20 drymies on a hedge u put 20 of the drymies charm inside the inventory of the addon's version of the hedge.
the addons version of the drymies Hedge and whirlsprigs flower workstation would probably be separate blocks u make with the apparatus/imbuement_chamber.
For "simplicities" sake the math of both of them for production would be the same as their base mod counter parts (just charms in the block instead of Drymy/whirlsprigs bound to feed them)
(if a wixie version did exist it would probably require more thought as its not a workstation that accepts multiple charms as is)
it would be tps efficient but doesn't take away from the costs of running the blocks resource(charms and source) wise sans tps
optional Bonus: if theres compat for when the addon Ars elemental is also installed a entity-less version of its prismarine Siren fishing home
