The players can earn Stygia while farming the reputation of Ve'nari. You can also earn them for completing daily and weekly quests found within WOTLK Gold The Maw, though this increases players' Eye of the Jailer more fast than any other means to earn Stygia.
It is important to be aware that each of these activities will earn certain Eye of the Jailer points. Each of the five levels of Eye of the Jailer, the Jailer will send more enemies to attempt to take out the player's character. At Level 5. Jailer will siphon off the character's life force each 10 seconds until they die. Each level of Eye of the Jailer requires 1.000 points to get there. Daily quests and weekly quest for Perdition Hold/Beastwarrens and Hunt completion all come with 1 000 Eye of the Jailer or more, making these the most risky methods to earn Stygia.
To best farm Stygia, players should focus on completing quests early into the workweek. Then, they will be able to concentrate on killing enemies. If they are able to notice your Eye of the Jailer meter being too high, it is possible to go to Oribos to avoid getting killed and losing their collected Stygia.
It is up to the players to decide on spending Stygia. Some players would rather purchase any upgrades that are permanent from Ve'nari first, such as Torghast permanent upgrades followed by improvements for buy WOTLK Classic Gold the The Maw. Some will choose to save money for more conduits or sockets.
