Items that require x victory to release something?

[Shadowcran]

In Dark Side, there is an Alchemy Set(well, 2 in total) you can get from Simon, the magic guy you recruit from the Magic Tower in Monteville. Every 10 victories, you 'use' it for a talent rune.

It's 50k gp, but over the course of the game, more than pays for itself. It doesn't get equipped, just remains in your inventory so there's that bonus as well.
The first one is from Simon, 2nd varies.

Since you get Simon rather early, usually first recruit after dragon, you'll get a lot of use from it.

Oh, and just like the other items, Gremlin tower battles don't count.

There's also a skull(in every version so far)that's a bit different but works kind of the same. You have to equip it for X battles, X being what takes it from 100% to 0% charge. You get more rage, but half your mana is gone every battle with it equipped. Once it reaches 0%, it's worth it as it becomes a better skull that gives +5 Intellect AND +5 Attack.Pain Skull becomes Death Skull.
