Epitome of Elements

While you were looking for a vessel, I did some prepping – I boiled tinctures, evaporated them, mixed the resulting extract with a rare decoction. But the last component must be gathered by the spirit seeker. So, listen and remember!
It shall be just like a sea creature, slithering in the ocean, fed by water.
It shall be like a free-spirited bird, circling in the air, carried by wind.
It shall be like soft clay, hard as a rock and porous like sand, fed by earth.
And enemy's hot blood must wash the hand of the one whose heart burns with untamed fire!
You should collect all four symbols of elements. Don't buy, trade, or receive them as gifts. Get them yourself. Only then the spirits may hear your request.

Yes! I sense power of four elements behind you. Spirits await you!
