Let’s come up with a monster.

It would be much better to focus on making creature abilities more original! For example, a level 7 monster – Wrath of Nature! A fusion of all the plants, fungi, and trees in the world, with the heart of animals of all kinds! This "fusion" can be used as a tank, with an archer or pikeman placed on it. Abilities: "Shelter," "Vulnerable to Fire," "Large Creature" (4 cells), and "Vines" – the latter would be useful during a siege. It extends vines through the castle walls, allowing a warrior to pass through.
