"Psijic Order Skill-Line with Summerset Isles
This is not the full list, I can only remember some of the abilities/passives.
Undo
When activated, you will regain your resources that you had 4 seconds ago. One of the morph also makes it possible to activate it while you are stunned.
Meditate
once cast, the player enters a meditative state, restoring Health, Magicka and Stamina every second. One morph grants you more resources per second, while the other gives you Major Protection during the channel. The skill can be bashed, but is not otherwise interrupted by incoming damage, although you are locked in place while channeling and cannot move.
Time Stop
This skill involves the player selecting an 8-meter radius area, and players in the area immediately begin to slow down. After 1.5s, any target within the radius of the skill are frozen-in-time for an additional 3s. If you manage to get out of the area before the 1.5s cast completes, you’ll be safe – but otherwise, this is a hard stun, very similar to the stun from the Warden Sleet Storm ultimate – it drops block and roots you.
Imbue Weapons
Casting this skill applies a buff that adds extra Physical Damage to your next two Light Attacks for 2s. One morph turns this into a Magicka skill and applies a random status effect (Burning, Concussed or Chilled). The other morph heals the caster for 15% of the damage done.
Acceleration
This skill is an instant-cast Magicka skill that grants you 3s of Major Expedition and 12s of Minor Force. One morph reduces the cost of Sprint by 50% for 12s, while the other morph becomes a channeled skill, but triples the duration (to 36s).
Unknown Skill
Your Light attacks now heal your group members.
Unknown Passive
You gain a 10k shield while blocking, this slowly recharges after you drop block."

Time Stop: Slow down the passage of time so slow it eventually freezes, stunning all enemies in the area.
Imbue Weapon: Enhance your weapon with energy, causing the next Light Attack to deal additional damage.
Acceleration: Bend time and space around you, increasing you movement speed and the power of your Critical Strikes.
Mend Wounds: Invoke the Rites of Moawita replacing your next Light Attack with a heal over time, or your next Heavy Attack with a channeled heal.
Meditate: Learn to focus your mind into a relaxed state to restore Health, Magicka and Stamina.
Undo (Ultimate): Walk backwards through time, reappearing at a prior location with the exact same Health, Magicka and Stamina values from 4 seconds prior.
