When to cast Wall of Stone

Cast it to split a fight in two. Wall off the archers and casters at the back and deal with the melee first, or wall off half of a big group so the rest have to path around. Enemies with no line of sight cannot target you, and the AI is not great at walking around obstacles.

Each pillar has 30 Hit Points, so a determined enemy can smash through, and Force and Thunder damage do double. Against casters with Magic Missile it will not last. Against a room of melee brutes it holds for a long time.

It is Concentration, which is the real cost. Your caster spends the fight holding the wall instead of holding Hold Monster or Haste. That is worth it when the wall removes half the enemies from the fight, and not otherwise.

It also works the other way: put a wall between a wounded ally and the thing chasing them and buy a turn for a heal or a retreat. No save, no roll, it just appears.
