Katakuri and Doflamingo stopped their duel. Su Xiao stood at the edge of the mochi area, refraining from stepping in for the time being.
Before confirming something, Su Xiao would never recklessly get close to Katakuri; specifically, whether Blue Steel Shadow was effective against Devil Fruit Users, or whether activating Blue Steel Shadow would allow him to injure Katakuri.
Katakuri's body could transform into mochi, rendering ordinary cleaves ineffective. Blue Steel Shadow's ability damages the enemy, then annihilates energy within the enemy's body, causing True Damage.
Su Xiao seriously doubted whether cleaving through Katakuri's mochi form counted as damaging the enemy. If it didn't, Blue Steel Shadow wouldn't work, leaving him helpless against Katakuri.
Katakuri's Mochi Fruit was troublesome; this Paramecia Devil Fruit was even more precious than most Natural Devil Fruits.
In most cases, the value of a Devil Fruit is ranked Natural > Paramecia > Zoan.
