Hermits in the Peach Blossom Garden are best matched with rubies or emeralds. The reason is given by quick answer.

In fact, this does not conflict.

First of all, not all the equipment in Taohuayuan can play a certain kind of gem, but there is a fixed limit.

For example, emeralds belong to the output and can only be played on weapons, rings and wristbands.

Ruby belongs to the Ministry of National Defense and can only be played on belts, helmets and clothes.

Related to rubies are sapphires and topaz of the same defense system. (Physical defense against gems)

Personally, I like these two kinds, but in terms of price, they are absolutely cheap. Blood volume is expensive.

In terms of durability, especially for pharmacists, it is similar. Ruby has a slight advantage. It's up to me whether I like it or not.

I hope I can help you!
