Blastoise (5e Creature)
From D&D Wiki
Medium elemental, any alignment
Innate Spellcasting (at will). The blastoise’s spellcasting ability is Dexterity (Spell Save DC 16). The blastoise can innately cast create or destroy water, wall of water, ray of frost, and false life without using any components.
Rain Dish. While submerged in water or outside during rain, the blastoise regain 10 hit points at the start of each of its turns.
Torrent. While the blastoise is below 50 hit points, the damage of its hydro pump attack increases by 2d6, and it suffers no disadvantage from attacking at long range.
Tackle. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage.
Hydro Pump. Ranged Weapon Attack: +8 to hit, range 150/600, one target. Hit: 19 (4d6 + 5) bludgeoning damage.
Shell Defense. The wartortle withdraws into its shell. Until it emerges, it gains a +4 bonus to AC and has advantage on Strength and Constitution saving throws. While in its shell, the wartortle is prone, its speed is 0 and can't increase, it has disadvantage on Dexterity saving throws, it can't take reactions, and the only action it can take is a bonus action to emerge.
Blastoise is called the shellfish Pokémon for whatever reason, even though it's a turtle. The water spouts that protrude from its shell can shoot bullets of water with enough accuracy to strike empty cans from a distance of over 160 feet.
