A magical component could be a fairy ring. Place mushrooms in form of a ring on the ground. particles should show, that the ring is complete. Is another crafting variant (drop items inside the ring)

8 Mushrooms formed as a ring:

3 modes of Fariy Ring:

• Normal: Default mode. Only some particle or textures on the ground. Drop some items inside the ring and when a recipe matches they are crafted together. Needs time and has some glowing effects near the ground
• Fairy: a shining ring appears and in the center of the ring is a fairy. This enables some new recipes (trading with a fairy). Put items inside and fairy trades it to some items of its world. (Fairy Stone - like Glowstone but pink, pink glowshroom, ...)
• Switching a Fairy Ring into another mode needs also a recipe and some time.
• entering the ring when in other mode than normal, the special mode terminates - we need another mechanism to get wrong items back instead of entering the ring - maybe when there is no recipe for this item, drop full inventory? (only in special modes)

Possible normal recipes:

• Grass - Infested Grass
• Dirt - Mycelium
• Grass Block - Mycelium
• Sapling - Dead Bush
• any Flower - Infested Flower

Possible Fairy recipes:

• Switching: Glowstone Crumbs + Flower + Feather + Gold Ingot
• Glowstone Crumbs - Fairystone Crumbs
• Glowstone Dust - Fairystone Dust
• Glowstone - Fairystone (pink variant of glowstone)
• any mushroom - Fairyshroom (like glowshroom but pink, but drops also)
• Water Bottle - Bottle with clouds
• Wet Sponge + any Wool - Sponge + Cloud Block (similar recipes with other water things)
• Gold Ingot - Fairy Gold Ingot
• Emerald - Rubellit

Fairy can look like this:

Possible witch recipes:

• Switching: Nether Wart + Mushroom + Rotten Flesh
• any Flesh - Rotten Flesh

Building a Fairy Ring and craft operation with particles is implemented. In first iteration only the normal mode is available. The Fary/Witch mode can be done later, if more recipe ideas and more content are added. :)
