Titan's Relic!
It was said that C'Thun defeated and killed Titans in the Battle of the Ancients, so it carried equipment like this. This proved that the rumours were correct.
Titan's Relic was an item that buffed all attributes and gave special Physical bonuses.
Basically, any Physical professional could use this item, but it was particularly suited for Paladins, Shamans or Druids because of its additional healing effect.
There was also a special effect that could reduce the Defense of any non-Boss target, which meant that this equipment was better for use in PVP. After all, most people would plow through monsters quite quickly, so reducing their defense didn't mean much.
The monsters they would be fighting would have to be quite hardy to require such an item.
