The elementals have always intrigued me and the lore on Thyrus is iinteresing.
It doesn't resemble a typical cnj/whm staff because its made from a petrified (great) tree. And since elemental reside in trees what if that weird looking thing on its top is a petrified/dead elemental? It'll explain its power.
It'll also explain why it looks like that. After looking around the 1.0 elemental oha sok kinda look like the tip of thyrus. Never played 1.0 so don't know now the other elemental look.
What do you guys think? Is thyrus a petrified elemental? If so HOW did it become petrified?
