Posting here, since I am not sure how to contact the original scripter.
The first part of the quest works fine. I placed the NPC and the Vampire Lords. then went and killed each of them (as admin) to test it. They have quite a drop and one even spawned paragon so the loot was awesome
As a tip to others: Unless you tweak the lords' strenght, I don't recomend spawning many monsters around them. they are quite a chalenge themselfs.
I used the knife on each of them and indeed they gave hearts. I returned the hearts and got pieces of armor. Once again all works great. Even the "2 click to change appearance" feature works.
At the 2nd part where you have to help Verona, I encountered 2 major problems. I took her bag with the crystals and went filling those. I wanted to keep my inventory clean so i placed the filled up crystals in the bag and stacked them. When I returned to her, the 2 problems were:
1. No matter how many crystals you take out of the bag, there will always be 1 inside it. This meaning, that if a player fills just 1 crystal, they can already return to Verona, since each time they take out the crystal, another filled crystal will apear in the bag.
2. I gave Vrona her 15 crystals (filled) and nothing happened. I continued giving her crystals (using the abovementioned bug) and still nothing happened.
Edit: I tested the quest on RunUO 2
