Inteleon (5e Creature)
From D&D Wiki
Medium elemental, any alignment
Sniper. The inteleon scores a critical hit on a roll of 19 or 20 and rolls the damage dice three times, instead of twice. Additionally, attacking at long range doesn't impose disadvantage on its ranged weapon attack rolls.
Torrent. While it has 35 hit points or fewer, the inteleon has advantage on attack rolls. In addition, it deals an extra 7 (2d6) damage to any target it hits with an attack.
Multiattack. The inteleon makes two snipe shot attacks.
Snipe Shot. Ranged Weapon Attack: +9 to hit, range 180 ft., one target. Hit: 24 (3d8 + 6) cold damage.
Focus Energy (Recharge 5-6). For 1 minute, or until it loses concentration (as if concentrating on a spell), any hit the inteleon scores is a critical hit.
