In mhw the Kirin Tree (dual blades) is:
kirin bolts>kirin bolts+>monarch
in mhw iceborn:
monarch>kirin bolts>kirin bolts+>wunderkirins
I don't own the dlc. In my game Kirin Tree looks like this
monarch>kirin bolts>kirin bolts+>wunderkirins.
Why? I don't have dlc, monarch should be the last one.
Also, materials used to craft monarch and kirin bolts are the same as in dlc.
