Can't equip sword stance on dual heat swords

[Stefan]

So, i have the iron phoenix stance, and i have dual heat swords (rank 26)
When i try ot upgrade it, the iron phoenix stance is not there, even tough it says it's for swords.

do they need to be max rank or something?

It uses Greatsword/Axe and Dual Sword stances. Meaning Cleaving Whirlwind, Tempo Royale, Rending Crane for its heavy form, and Crossing Snakes and Swirling Tiger


whoops thought you meant Dual Dark Swords.

The Dual Heat Swords use the Dual Swords stances, meaning Crossing Snakes and Swirling Tiger. Iron Phoenix is for standard longswords, like the Skana.

Each type of melee requires its own Stance types. Hammers use hammer stances, longswords Longswords stances, etc. Leveling them up does two things. First, they unlock more combos with that stance. Second, they add additional mod capacity. Maxed stances on the proper polarities give up to 10 extra modding capacity.

Longswords are a single sword and do not share their stances with dual swords.

A single dagger stance is not equippable with dual daggers - even if both daggers are identical to the single.

Dual Heat are a longsword and a big knife and so are even more unlike a single Heat sword.
