Can a paladin/fighter plant a tower shield in the ground? What are the benefits that can be obtained from this? I'm thinking more like using Hide action or gaining half or 3/4 cover.
Clarification: I'm not asking about rules-as-written. Basically I want to check how this should work if this is allowed.
A giant fighter wants to plant his tower shield on the ground mid fight to create a cover. Does he need to do a strength check if the shield planted correctly? If he succeed, can he hide behind the shield? What benefit he has? Can this be done by medium creatures?
