Where did the fashionable elf stone of Rainbow Island come from?

That elfin stone is a replica. If you are lucky, brush a snake dragon and you will explode four or five. If you are unlucky, you won't explode a snake dragon after brushing it several times. The effect of * * * can only appear if you are equipped with a constellation cloak. This effect is reflected in the fact that when you stand still, there will be a blue halo under your feet. When you move, a beautiful blue band will follow you. This cloak can be bought in the mall.
