So, If we going off DnD rules. This Wizard is level 20. He just used Teleport a 7th level spell and the Control Weather spell that' a 8th level spell. Where you can choose how you want the weather you want to be. But it does take 1d4 x 10 minutes for the spell to take full effect.
But let's just say were out of combat and the DM is feeling nice and happy that the darn Wizard is just not just using Fireball to fix all there problems for once.
Also he use the 4th level spell Fabricate on are dear knight friend Pebbles.
I think I got everything.
