A minorly interesting fact from the wiki. Lilypads of holyshitthat'shilarious actually have an effect up to 4 blocks above them.
So I can just move their pond down a block and slip the ritual stones in directly below the farmland for fun and giggles.
It also means the cabling for the planters is no longer in the way
PS. Redstone control for the rituals? Yes please
PPS. Anyone know if master ritual stones will accept redstone signal from an enderIO conduit thingy? It's my goto solution for wiring in tight spaces.
PPPS. What is the horizontal range on the ritual? Is it only active above the 3x3 footprint of the ritual stones? If so, i'll need a few more of the bloody things
Update:
EnderIO redstone conduits between a block with a lever and each of my master ritual stones apparently won't deactivate the rituals. Is that a mod incompatability or something about it being a persistant signal rather than a timer?
Also the wiki says each should use 20LP/s. Try more like 500 if the numbers my divination sigil was showing were correct.
