Sir Lindeal is dropping the Testimony from the Soulfire quest.

This also is working for the Sir Lindeal Testimony Quest.

The Soulfire Quest can remain the same

Loveal S`Nez should accept Sir Lindeal's Testimony.

Sir Lindeal drops 'Testimony' which is required for the neriakc quest.

This is the same item that is obtained by doing the Merko Quetalis portion of Zimel's Blades.

If you have evidence these are different items, please share.

I was going off of the wiki which said they were different. But that's the only proof I can find. My research actually leans to you being correct!
