Crystals are used to catch Terra Monsters, they come in many different types, but they all function the same way. Crystals can be bought from the World Store , under the Crystals tab, won on the Slot Machine, given as quest rewards or very rarely as drops from wild Terra Monsters.
To attempt to catch a Terra Monster, click the Crystals button in battle, select the crystal and click it. An animation will show of your crystal trying to capture the Terra Monster. If you are successful, the sprite will fade and the crystal will fade, then the Summary Page for the Terra Monster you just caught will pop up. If you fail in capturing the Terra Monster, the crystal will try unsuccessfully several times before fading away, and battle will continue as normal. However, you will have used up your turn in that round of battle.
There is only one guaranteed way to catch a Terra Monster without fail, and that is to use an Advanced Mega Crystal. However, these are very expensive and should only be used as a last resort, it would be much wiser to use Super Crystals, or if you can afford them, Advanced Crystals of your chosen element. There is always a chance your crystal will fail, and you will not be able to get it back.
Some Terra Monsters have a higher catch ratio than others, this is usually dependant on rarity, but the resistance bar plays a major role in your attempt at success. Make sure the resistance bar is as low as possible before throwing your crystal for the best chance to catch the Terra Monster.
