World of WarCraft players who have reached level 90 and are looking for a diversion are being offered some tips on class management, courtesy of publisher Blizzard.

The company has posted video guides for playing each of WoW's 11 classes at level 90, including Death Knight, Druid, Hunter and Mage. This year's upcoming expansion, Warlords of Draenor, allows players to immediately level up to 90 and offers paid level boosts.

"Want to leap into action with a new class at level 90 but not sure how to begin?" asks the company's Battle.net website. " In our new videos, one for each of WoW's 11 classes, we'll give you a crash course on how to play your new level 90 character. To help you get started, these videos focus on one damage-dealing (DPS) specialization for each class."

For example, the two-minute Mage video (above) shows players how to deliver the most damage without draining too much mana cost. It shows the spells that ought to be cast before picking a fight with a noteworthy opponent.
