Beryl (Cave idea)

Beryl is a ore that can seen in deep dark caves, These crystal are used for creating chemicals and upgrading Shields, Since shields are been added in 1.9 as combat update, There only one variant of shield is regular shield, This crystal can upgrade the shield into beryl shield, Also Minecraft hasn’t added chemicals so Beryl is perfect fit for caves and cliffs update, Also I almost forgot about Beryl one more idea is a course beryl tipped arrow, Well it’s an idea for fletching table since it been added in 1.14 as village and pillage update but it hasn’t have a purpose so that why I made this idea for caves and cliffs update.
