[Bug] my Draconius got lv 34 but no new skill gained.

You must of replaced blinding smoke with another skill book and if you did that you won't get wild fire

How can I know that new skill will not replace skill book T_T,
so How can I get wild fire then

You'll have to try and get it from advanced fire bookchest from volcano expert, from chest you'll have chance to get wild fire, meteor (aoe magical), fire blast, fire bombs and super fire bombs. Not sure if there is a super fire blast as never seen it.
