Hundred-Handed One

The giant can take one reaction on every turn in a combat.

The giant can't be surprised.

The giant makes four longsword attacks or two rock attacks.

Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 21 (3d8 + 8) slashing damage.

Ranged Weapon Attack: +13 to hit, range 60/240 ft., one target. Hit: 30 (4d10 + 8) bludgeoning damage. If the target is a creature, it must succeed on a DC 21 Strength saving throw or be knocked prone.

The giant adds 5 to its AC against one weapon attack that would hit it. To do so, the giant must see the attacker and be wielding a melee weapon.
