Recharging Ring of Shadow

[Tudana]

I read up on recharging from the P99 wiki Recharging Guide. So I wanted to try it out on this ring.

Sad to say the method did not work, i lost a fully charged ring and the empty ring I had, which i wanted to recharge. I used the inn Keeper in Rath mnts.

A couple years back, I first learned how to recharge my Leatherfoot Raider Skullcap with the raiding guild I was in. We used the fishing hut in WC exclusively, i wasn't sure at the time if it was on purpose or just convenience.

Now following the guild on the p99 wiki it doesn't say any particular vendor or zone, it just says

Step 2: Find a merchant that people don't use very often. You want to be able to sell an item to a merchant and see it in their items for sale list.

My question is this, is the best way to find a "rechargeable" vendor is to sell the vendor something junk first to see if it shows up?

Reason I ask this I see words, pages, bat wings or bones etc from time to time at vendors, and i know people have sold these items and it became part of his inventory.

what am I missing... i seen these items on the vendor i used. So I didn't test the "trash sale" first and my Ring of Shadow was not there, I closed the window, I even finally camped and relogged. Still no rings.

Any advise would be appreciated
