The Psijic Order skill line has a support-focused, time manipulation–themed set of skills. You’ll find it complements just about any build but doesn’t fare quite as well when used as your exclusive ability line. You’ll find a lot to love here if you spend some time in the PvP Battlegrounds—especially Undo, which allows you to rewind your Health, Magicka, Stamina, and position back to 4 seconds before using it.
The trick to the Psijic Order is the way it levels up. While it’s not nearly as labor-intensive as the Mages and Fighters Guilds, it still takes a good bit of effort to max out. You’ll need to complete quests for the Psijic Order in order to level up the skill line. There are 10 quests, each of which will earn you an extra level in the Psijic Order, unlocking new abilities at the same time. Where this becomes a challenge is the quests themselves. Nearly all of them involve traveling across the whole of Tamriel to track down breaches in time. It’s a peaceful journey, exploring nearly every region in the game, but it takes an awful lot of time to complete. Be prepared for a big time commitment if you want to reach the end of this skill tree. It’s definitely worth the effort, but it is not for the faint of heart or those who are light on time.
