This magical battleaxe was created in the forge of Kavaki the Ram Lord, creator of goliaths.

Cleave Stone - As an action, you can swing this axe into a nonmagical stone or stone-like surface¹, causing the ground to rumble and a fissure one inch wide to appear. The length and depth of this are both equal to 5 + your level, rounded down to the closest 5-foot increment. If a creature is standing in a space where the fissure appears, it must make a Dexterity save against a DC of (8 + your Strength modifier + your proficiency bonus) or fall prone. Creatures are immune to this effect if they are Large (until 5th level), Huge (until 10th level), or Gargantuan (until 15th level). ¹Whether or not something is "stone-like" is determined by the DM, but the substance should generally be strong and brittle, such as hardened clay or glass. You can use this feature a number of times equal to your proficiency bonus per long rest.

Proficiency with a Battleaxe allows you to add your proficiency bonus to the attack roll for any attack you make with it.
