Multiattack

The green knight makes two attacks: one with its battle axe and one with its shield bash.

Battle Axe

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage, or 9 (1d10 + 4) slashing damage if used with two hands.

Shield Bash

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) bludgeoning damage and the target is grappled (escape DC 15). Until this grapple ends, the target is restrained by magical vines springing forth from the green knight's shield, and the green knight can't make shield bash attacks against other targets.

Javelin

Melee or Ranged Weapon Attack: +7 to hit, reach 5 ft. or range 30/120 ft., one target. Hit: 7 (1d6 + 4) piercing damage.
