Blessing of Demeter

during spring+summer, lands are more fertile when you stand on them. You can always cast druidcraft. When you try to grow plants, you will always succeed. When you have sex, it will always produce a child.

During winter, you are immune to cold damage, and when you attack with a weapon, you can deal an extra 1d6 lighting damage. You can do this a number of times equal to your proficiency bonus and it recharges on a short rest. The damage increases by 1d6 at levels 5 and level 9.

You also get access to the ability to cast certain spells at certain levels using the mental stat of their choosing for their spell casting modifier. You can cast each only once per long rest.
