Gbahali

Armoured like a crocodile, longer than a canoe, and faster on land than anything that shape has any business being. It lies up in the reeds through the heat and works the riverbank paths at dusk. The people who fish that stretch will point out where it beaches and where it does not, and they are right about both, and they will not go with you.

Rush: piercing, melee 10 ft, +4 to hit, 3d6+3, and it covers open riverbank faster than a person runs. Death Roll: against a creature it has hit this round, no attack roll and no save - an automatic 3d6+3 as it takes the target into the water and turns over. Cooldown 2 rounds.

Plated: DR 2 against everything that is not aimed at the eye or the soft throat. A called shot at either, taken at Disadvantage, ignores its DR entirely. Amphibious Patience: it can lie submerged and motionless for an hour and cannot be spotted while it does, and it will happily spend that hour.
