Bella needs them until she runs out of divinations! There's a lot of combinations to go and they will not run out today.
"I do hope to invent arcane healing eventually! The spell that does stuff to undead will probably wind up being important, undead are healed by an energy that hurts everything else and harmed by an energy that heals everything else. This is totally healing research. Among other things. Eventually."
"Well, that and this is the only place I can teleport to. So far."
"We don't generally want teleportation everywhere, there are lots of areas where a great deal of foot traffic would disturb delicate plants and we manage that by making it sufficiently inconvenient to get there that only people who really desire to go will do it, and therefore the wear on the land is managed while no one is forbidden from anything."
"I will aim to invent flight first," she says. "That should have fewer problems and serve most of the desiderata."
"No. I mean not with the conventional flight spell, a polymorph could do that but if I remember right that's harder."

I didn't say anything. She strolls past him to go check on her houseplot.
