Can you do a reaction that turns a drone in to a queen like for mages?
yes. that's how you create queens. and it doesn't even need to be a drone, any wasp will do. the thing is, you have to sacrifice 10 wasps first, so it's not immediately available on embark. you'll have to wait for a migrant wave or two.
Anyway, I am currently trying to make it so that the queen lays 8 eggs every 2 seasons. I have currently encountered a roadblock. Currently I've been testing the queen features by increasing their pop-ratio and disabling the queen fighting interaction. This usually makes me end up with multiple queens but that wasn't a problem till now. I now have to make sure that the eggs are coming from one specific queen since, if one queen lays 14 eggs and another lays 2, that still creates an average of 8.
Since we were going to do this eventually I think it's time to brainstorm ideas that give you a guaranteed queen on embark now.
ok, here are our options:
one way to make it would be to give the queen the PET tag. but that causes a whole bunch of troubles, from queen pets arriving with migrants, to queens being sold in waspen caravans, so it's out of the picture.
we most certainly can't work from the entity file, i already tried that.
brain essences are considered a tool. if we made them available on embark (i think it can be done from the TOOL tokens in the entity file), then the player could buy enough to make a queen before embarking (at an affordable price, but not very cheaply. wasps don't need a lot of stuff on embark), and then construct the Hivemind and immediately upgrade a wasp to a queen. you'll have to spend a few points, but it's the next best thing. we can rationalize the fact that the essences are made from things like spore wood by saying that this is actually where the essence is stored, not the actual essence.
this also has the advantage that it opens up another way to play the hive: rather than maybe taking enough for one queen and then expanding your hive by gradually receiving migrants and setting up industries, you can buy enough for 2 or 3 queens and rely on the steady swarm of wasps that they will produce rather than a standing army and war animals for your nourishment and protection. this will come at the expense of skill points, other tools and generally you'll have very few supplies. all in all, a hard but fun way to play the wasps.
you will also be able to order them from caravans later on, and so you don't have to continually micromanage which wasps to kill and which ones to preserve if you want to make a second queen, prolong the life of some skilled wasps or enchanted weapons (nobody raised any objections, so i modded in an enchantment system like the one i was talking about)
