Lu Li’s ring could only be upgraded by exchanging a sacrificial offering into energy, or at least, that is how it was done for the first three levels. Hence, there was a need for an altar that could supply energy to the ring.
In saying this, the Altar of Tides was not the best option out there. Perhaps there were other altars that could provide a better upgrade for the ring.
However, the Altar of Tides was the best altar that Lu Li could get his hands on. It wasn’t just a random altar built on a deserted island – it was one with a long history.
Stranglethorn Vale appeared to be the only peace zone in Azeroth where the war had not yet breached.
Within the Vale resided a great Troll civilization from the ancient past. They had built grand cities that the Trolls and Goblins lived in.
Most of the Trolls still followed the tradition of eating humans and a few of the troll tribes had already been recognized as man eaters. These included the Mossflayers and the Vilebranches.
