Ball of Blades (5e Creature)
From D&D Wiki
Ball of Blades
Large construct, unaligned
Saving Throws Str +10, Dex +7
Immutable Form. The ball is immune to any spell or effect that would alter its form.
Magic Weapons. The ball's weapon attacks are magical.
Roll Out. When the ball moves through a creature's range and provokes an opportunity attack, the creature has disadvantage on the attack. The ball can also use the Dash or Disengage actions as a bonus action.
Multiattack. The ball makes four blade attacks.
Blade. Melee Weapon Attack: +10 to hit, reach 15 ft., one target. Hit: 11 (1d12 + 5) slashing damage.
Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 15 (3d6 + 5) bludgeoning damage.
Blade Storm (Recharge 5-6). The ball unfurls its blades and spins around rapidly in place. Each creature within 15 feet of it must succeed a DC 20 Dexterity saving throw. On a failed save, it takes 31 (4d12 + 5) slashing damage and is bleeding for one minute, unless it is a construct or undead. While bleeding, the target takes 9 (2d8) damage, until either the effect ends or the creature is healed. On a success, it takes half damage and is not bleeding.
Aggressive. The ball moves up to its speed toward a hostile creature that it can see.
Rampage. When the ball reduces a creature to 0 hit points with a melee attack on its turn, the ball moves up to half its speed and makes a blade attack.
The construct known as a ball of blades is exactly as it sounds: it's a large sphere that opens to reveal an armory's worth of blades. These massive constructs are swift attackers that are generally created either as guardians of winding hallways or as shock troops in armies that use constructs.
Constructed Nature. A ball of blades doesn't require air, food, drink, or sleep.
