Siege Frenzy

You are unwilling to part with the weapon, always keeping it within reach. You have disadvantage on attack rolls with all other weapons, unless no weak buildings or structures are visible within 60 feet of you.
When within 15 feet of such, you must succeed on a DC 15 Wisdom saving throw or enter a siege frenzy. Whilst in this frenzy, you must use your action each round to attack the trigger of your frenzy until it is reduced to rubble.
