Last week I squeezed in a third attempt at a public quest in the Velious area and had some success this time, unlike take two. This time I followed advice of Bhagpuss and went for the Echoes of the Ring War PQ (wiki link) instead.
The fight was simple, following a checklist of kills of ghostly orcish invaders.
The end result this time was a chest with some nice items in, no bugs to be found. There was only one other player in the PQ at the time so it didn’t scale up beyond basic mobs and some giants to slay, hence the reward chest was equally modest in size.
I’ve seen what the system offers, but given the lack of interest among other players it’ll be more rewarding to stick to questing in future.
