If enchanting the weapon with more sharpness and lethality was all that Sword Qi could do it would have never been revered at the first sign of a Martial Master!
When it was all constricted to close-quarter combat, it was naturally more effective to just use that form. However, in a situation where close contact was threatening the true value of Sword Qi shone even more.

Since this was mostly used when hunting Monsters and True Beasts in Murim, it was also fitting for Leo to use it against a monster like the Lava Golem!
The first thing Leo did was coat his whole body with Internal Energy in case something unexpected still happened, but he at least didn't want to reveal that Tank aspect of his abilities.
He was going all in with the attacker Role!
Swish!
