Avandra's Oasis

You bless your campsite as a waypoint for travellers in need. Within a 10ft radius centered on you, rain does not fall, wind does not blow, and creatures automatically pass any saving throws for extreme heat or cold. Creatures outside the radius have disadvantage at detecting creatures within it.

When you cast the spell, you may also choose to summon a wellspring to provide clean, potable water.

You can cast this spell again while it is active to maintain the campsite's existence for another 24 hours. You can create a permanent oasis by casting this spell in the same location every day for one year.
