Caligati Dimachaerus (5e Creature)
From D&D Wiki
Small humanoid (caligati), chaotic evil
Multiattack. The caligati makes two attacks with its gladius.
Gladius. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) piercing damage.
Parry. The caligati adds 2 to its AC against one melee attack that would hit it. To do so, the caligati must see the attacker and be wielding two light melee weapons.
Because of the widespread use of gladii, this is one of the first fighting styles adopted by the caligati. It is used by literally every culture, so the caligati have had many opportunities to adapt it and learn new variations, deciding this is the best.
