Hey friends, I'm back with another spell to explain a thing an NPC is doing.
Players will have access to this one if they jump through a shitload of hoops, so I'm trying to sanity check it. It has to stay at 5th-level for reasons.

>what if Wall of Force was a one-hour ritual, also bigger
Does this need a material component with a cost?
How much would be fair?
