Wake Up

The spell awaken requires the material component: “An agate worth at least 1,000 gp, which the spell consumes.”

Which seems reasonable, as the spell is powerful. Agates can be found in the gemstone tables of the Dungeon Master’s Guide, on page 134. Three of them there actually. All on the 10 gp table. To cast the spell you need a gemstone a hundred times as valuable as any treasure. Which you imagine might be hard to find and is probably pretty darn large.
