How to activate the crystal device?

[BookerGrimm]

I have collected two crystals and they are shown in my inventory but how do I activate the stone device at the home?

[Gunfreak]

Place them in the sockets/rings around the big stone.

Only colored crystals will power the device. The fragments that you find can only be used to upgrade the power of the elemental crystals that you pull out of the stone golem-bots heads.

Those stone golem bot crystals can be placed in the rings at the house and they will be powered within the device so you can augment them with crystal shards....

Word of warning.... crystals only merge once, so if you were thinking you'd be able to merge 4 singles into two doubles and then merge two doubles into a quad and then 2 quads into an octo.... forget it....

Near as I can tell the extra crystals are worthless....however they still count towards the seal on the cave door.

Crystals have three levels.
You combine a lvl 1 with a lvl 1 to get lvl 2.

Then you combine a lvl 2 with another lvl 1 to get max lvl 3.

You need three lvl 1 crystals to get to lvl 3 and unlock the most powerful spells.

Yeah, that is the max, and any that you get after that will turn into shards when you try to merge them with a level 3.

But if you have two level 2s you can merge them into a level 3 and get some shards.

Merging two level 3s gives only shards.

The power level of the discipline the crystal color represents is limited to 3.
