Cover is great when you can get it. The +2 bonus to AC/saves for ½ cover and +5 bonus to AC/saves with ¾ cover can be godsends with bounded accuracy when fighting against spellcasters and archers. Heavily wooded forests and dense metropolises provide plenty of opportunities to take advantage of this if you have a generous DM. In environments such as deserts or open fields, cover is scarce to non-existent.
I am trying to figure out a way for the wizard of our group to create cover for us when a lot of ranged enemies appear. I imagine he would cast a spell at the start of combat to create cover (no long cast spells or rituals).
What Wizard spells are capable of providing ½, ¾, or full cover for one or more PCs, without preventing them from moving or returning fire?
The Wizard is level 13 so has access to 7th-level spells. Feel free to include 8th or 9th level if you want, but it’s outside of the scope.
An example of what I mean by something that would provide protection and cover but prevent movement or return fire is Tiny Hut (which doesn't fit my demands because it is a ritual). The attackers wouldn’t be able to attack you, but you also wouldn’t be able to hurt them. I am not looking to avoid confrontation by making an impenetrable hut, going to another plane, etc. I want to create cover and attack after they do.
