It seems that if a wizard can prepare wall full of daggers in his room, he can throw a lot of them against any intruders. Say, a 10th-level wizard have +6 Int bonus (20 +2 from item) cast a telekinesis. He can throw 250 daggers at +11 attack bonus. Assume an enemy fighter have AC of 25, about 30% of them will hit, thus causing 75 d4 =187.5 damage in average. Ouch! Am I missing something?
