You call forth a monster from the depths. It manifests in an unoccupied volume of water large enough for it to appear in that you can see within range. When you cast the spell you can summon any Monstrosity or Beast with an innate swimming speed and a challenge rating of 8 or lower (e.g. Sperm Whale)
The creature is an ally to you and your companions. In combat, the creature shares your initiative count, but it takes its turn immediately after yours. It obeys your verbal commands (no action required by you.) If you don't issue any, it takes the dodge action and uses its move to avoid damage.
At higher levels
When cast at 7th level, the creatures challenge rating increases to 10 (e.g. Malformed Kraken). At 8th level, the creatures rating increases to 14 (e.g. Juvenile Kraken, Reduced Threat Dragon Turtle) and at 9th level increases ti 23 (e.g. Kraken or Dragon Turtle).
