Heavy Boulder I

CLANG! CLANG! CLANG! Several soldiers and adventurers swung pickaxes at the five-meter-tall boulder blocking the wall's gate. "Hurry! There are people in need of healing behind it!" the local commander shouted.

"Damn it. We know!" One of the adventurers growled, "This boulder isn't budging!" 

"It survived the dragon's breath and was blasted all the way here. Don't expect us to crack it with iron picks!" One of the soldiers threw his pickaxe away. Its tip had flattened from the constant use.

"Wizard!" The commander then glared at the mages in the back.

"Don't look at us. The boulder is too big, and you'll need a sixth-level spell slot to move it. And even if we did, we can't move it that far away." One of the wizards, a woman replied. She walked forward, extending her staff at the boulder.
