Fjordur:

Standart rate, 100 (1 stack) stone for 5% taming lv 60 gacha.

Just take a Dismodus and Doedic (needed for gather stone in the realm - choose the green realm for peace) if needed, take an argentavis too for carry the stone (take more stone for if somwthing go wrong)

There's you will no be able to place billbiard because "pillar tag".

Just follow a gacha you want to tame, when it stop. Throw your stone (100 - 300), it will eat continoustly, if the stone close to disappear, take the stone and throw again, do it until it tamed XD
