Roulette for the Enemy

In Land of Legends, all battles with enemies take place in a roulette game, which allows you to create a special spell that drives the enemy away. To make a spell, you need to collect a certain sum of numbers by spinning a roulette wheel. Every time you spin the wheel, the roulette arrow stops at a certain number. As soon as the number sum reaches the required value, the enemy will be defeated. Every time you spin the wheel, you spend a certain amount of energy. Sometimes you will have to spend a certain resource to unlock the roulette. For example, to fight the ghosts, you will need a certain amount of lavender - otherwise, the roulette will not open.
