[dev1301] Excalibur

I've been a fan of the Ultima Weapons in the various Final Fantasy games before Final Fantasy XI and I viewed Excalibur as XI's answer to that with its Additional effect of damage varying based on HP. I have been considering this upgrade for awhile as something to do after I finished Aegis. The other day, however, I found myself wondering if I would since I found a player with it fully upgraded and noticed that, on the final stage, the Additional effect was gone. I have not seen this on any other Relic, Mythic, Empyrean or Ergon weapon where something was removed completely. What I am wondering is this - is it really gone or is this an error in the item description?

Its an error in the item description, the Added effect is still there as far as I know.

Thanks for the response! I figured it was because it was there in the Japanese description shown during the presentation last year when these upgrades were announced. I am curious too as to why they decided to give Mjollnir and Gungnir 3 effects for their aftermaths and all other Relics got just 2, but that's a different discussion.
