As a fellow anonymous who lost their username and now can't access the wiki, (because there's no "forgot username" option and you can't sent a "forgot password" to an e-mail without a username,) this probably isn't necessary. Pretty much all specials take down about 10 durability. Moonlight Greatsword, Sacred Chime Hammer, etc. lose about 10. The only two I can think of that this isn't true for (off the top of my head, mind you) are the Smelter Hammer and the Curved Dragon Greatsword, both of which are notably physical attacks.

He must have not known that special abilities do that, which is pretty understandable

I'm super late but yes the strong attack has good aoe potential and the damage is high (and powerstanceing this and the aged smelter sword is evan cooler)

Why does this have 5 downvotes he just asked a question

Because people here are dumb

I'm going to say it isn't if you're looking to do a Strengrh/pyromancy build. The are is certainly nice scaling is very low compared to a Greatsword with a fire Drake stone and using the R2 too often will break the sword. Use only if paired with another for maximum damage.
