Been messing with secret interactions, did a rework of the Birth sphere; now instead of summoning a creature they make a female unintelligent for like 2 weeks. Any male can impregnate them in this state, and the pregnancy doesn't terminate when they get their intelligence back. It doesn't interrupt their ability to do work or anything, though technically they won't gain any skill experience.
But, it works better than summoning to get 1) an actual child, born to the woman in question and 2) the child will be a member of your fortress from the get-go, unlike summoned units that have to petition and are technically pets.
Technically, I can also turn men into women for the duration of a pregnancy, which is 6 months since they're considered an animal when they become pregnant.
this seems like a prank to toss on to folks adv mode wise.
a sphere dedicated to birth that doesn't work because it pulls off basic fort mode loop holes that also won't work if their souls occupation just says no, be it the other route requires adv party members to even work given summoning units don't work player wise at the moment.
any way personally found out the magical rock stuff can be used as crafting material if you have any use artifact tokens in the reaction but magical items are barred from this and if you dfhack the item to be used in a reaction it doesn't transfer the magic effect on to a different item and just behaves similar to the magical rock being used as a crafting material.
