206 durability each strike , what I can do with this sword

Collapsing Blade exchanges your durability for more power. I'm assuming this is what you're using most of the time?

collapsing blade is a skill that deals amazing damage but in return u lose a lot of durability.

It usually only lasts 5 hits before a fully repaired weapon becomes unusable until repaired.

I advise u to use it as a bossing skill rather than a mobbing skill and have seperate weapons for mobbing

planning it too , luckily I have other Excalibur to grind with 3-3-2 rank skill , deal 2-3k dmg each strike
