Online:Rune Prison

Rune Prison conjures a sphere of dark magic to disorient an enemy.  The duration of the effect is fairly long for a crowd control ability.  The Rune Cage morph  will do damage if it lasts the entire time.  Defensive Rune is cast on yourself and applies the effect to the next enemy who attacks you.

Notes
Defensive Rune was previously called Weakening Prison, with the same effect.  Presumably it was changed to avoid confusion with the Encase morphs.

Online:Dark Exchange

Dark Exchange allows you to sacrifice   to restore   and  . The Dark Deal morph switches this to sacrificing   in favor of   and  , while Dark Conversion reduces the   cost.
 
Notes
Dark Conversion is a recommended morph for the Sorcerer Initiate and War Mage builds, while Dark Deal is recommended for Arcane Warrior and Eldritch Mender.

Online:Daedric Mines

Daedric Mines summons 3 (or 5 with Daedric Minefield morph) mines in front of the caster, which will cause heavy Magic Damage and briefly immobilize enemies that trigger them.  It is among the more damaging of the Sorcerer's skills, but limited by the difficulty of use.  The mines do not arm for 3 seconds (unless you get the Daedric Tomb morph), and you have limited control over where they appear.  It is based on the direction your character is facing.  Without morphs, you get one a few meters in front of you and two closer up to either side.  Daedric Tomb will allow you to choose the center-point around which the mines are placed, and also removes the arming delay, and Daedric Minefield creates a larger circle of 5 mines in front of you.  The un-morphed version and Daedric Minefield may be more effective against larger groups of enemies, but Daedric Tomb can be more useful against fast-moving targets, as it is easier to hit them when you don't have the arming delay and can use it at range.

Notes
Only one set of mines (per player) may be active at a time.  Casting it again before the mines have been triggered or the spell has expired will cause any existing mines to disappear.
A single mine may damage multiple enemies if they are very close together, but usually this will not occur, as the radius of effect is quite small.
This skill may be more effectively used by the solo Sorcerer, and particularly one who does not make use of the pets from the Daedric Summoning tree.  The reason for this is that when enemies are distracted by fighting your allies, it can be difficult to lure them onto the mines.  The Daedric Tomb morph alleviates this somewhat by allowing the spell to be used as an instant-damage attack rather than just as a delayed trap.  On the other hand, skilled players may be savvy enough to intentionally lure your enemies onto the mines.  Just don't expect your pets or other allied NPCs to be that smart.
By casting the spell in confined spaces or on steep slopes, you can sometimes achieve a tighter grouping, making it more likely that all mines will be triggered.  This is an effective strategy when enemies are very close to walls or corners.
Some enemies, particularly flying ones but also some more powerful enemies, will be immune to the immobilizing effect of this spell.  This is not entirely a bad thing, however, as it makes it easier to get them to trigger all of the mines in a short time, which will kill them faster.
Daedric Tomb was changed from its original version in Patch 2.3.5 which placed all three mines in a row in front you instead of allowing you to place them anywhere.

Online:Restoring Spirit

Restoring Spirit reduces the casting costs, whether  ,  , and  , for all abilities, including those not in the Templar skill lines.
Online:Nova

Nova deals magic damage over the target area and reduces enemies' attack damage. Allies can activate the   synergy to deal additional damage and stun enemies within range.  Solar Prison changes the Synergy to  , which increases the damage and stun duration.  Or Solar Disturbance will reduce the movement speed of all enemies in the affected area.

Notes
Solar Disturbance is a recommended morph for the Templar Initiate build, while Solar Prison is recommended for Bastion of Light and Beacon of Hope.

Patch Notes
Online:Sun Fire

Sun Fire deals Fire Damage to the targeted enemy and applies Fire Damage over time, as well as giving a   boost to you.  '''Vampire's Bane increases the duration of the Fire Damage, making it more effective against single targets, while Reflective Light''' causes the spell to affect up to three targets with each cast, which makes it more useful against groups.

 
Notes
Damage ticks every 2 seconds.
Despite the name, Vampire's Bane does not do more damage specifically to vampires, except in as much as it is Fire Damage, which vampires receive increased damage from in general, though this is true of all three versions of this spell.
Vampire's Bane is a recommended morph for the Templar Initiate and Gleaming Champion builds.
Both levels of the Enduring Rays passive are required for there to be an effect on the damage over time portion of this skill.

Online:Solar Flare

Solar Flare deals Magic Damage to an enemy, and increases the damage of your next attack. The Solar Barrage morph changes this to an instant-cast, close-range attack.  Or you can choose Dark Flare, which reduces both your target's as well as other nearby targets' ability to heal (though only your primary target actually takes damage).

Patch Notes
Online:Backlash

Backlash deals a small amount of damage and copies all damage inflicted on an enemy and releases a percentage of it as a blast of Magic Damage.  Purifying Light causes a healing effect to remain attached to the target, restoring the   of all of your nearby allies.  Or you could choose Power of the Light, which converts the casting cost to use  , and changes the damage to Physical Damage.  It also reduces the target's physical and magical resistance, effectively increasing all damage taken.

Notes
When cast, this spell causes a bright beam of light to shine upwards from the enemy's location, which essentially marks it.  This can be useful as an indicator when playing in a group, hinting the other members of your party where to concentrate their attacks.  It's thus useful even if you don't use this skill yourself to recognize the effect when your group-mates use it.
This skill is most effective on tougher enemies, because it only deals damage at the end, so if an enemy dies before that happens, the cast was effectively wasted.  The Power of the Light morph is slightly more useful in such cases, because it also increases their damage taken, so it still does something even if the ending blast never fires, but either way, it's still preferable to use on monsters that won't die before it has a chance to work.
Purifying Light is most effective in cases where you want your allies to remain close to the affected target.  It might be unwise to use it in certain boss fights where staying within range of the effect would be detrimental.  (E.g. Fights where a damaging effect is attached to each player, in which case you do not want to be close together, or fights where the boss has a very powerful close-range attack.)
Purifying Light is a recommended morph for the Templar Initiate and Gleaming Champion builds, while Power of the Light is recommended for Luminous Warrior.

Patch Notes
Online:Eclipse

Eclipse reflects the target's spells back to them and explodes at the end of the effect, dealing Magic Damage to the target and other nearby enemies. The Unstable Core morph removes the reflect effect but increases the ending blast damage instead.  Or you can use Living Dark, which applies the effect to yourself and immobilizes any enemies that attack you, healing you for each attack.

Notes
This spell is mostly useful against spellcasters (unless you use Unstable Core).  The explosion at the end is still useful against all targets, but only if the target survives long enough for the blast to occur.
One subtle use for this spell is that it can be used against non-hostile targets such as bugs and rats, etc.  This turns them into tiny little bombs which will still deal area damage to your enemies.  With Unstable Core, you can set up a couple of them without actually alerting the enemy to your presence, so they'll go off during the fight.  So look around for those little critters if they happen to be nearby, because this spell can actually make them useful. 
Before Update 13, only the Unstable Core morph could be placed on an unlimited amount of enemies.

Patch Notes
Online:Blinding Light

Blinding Light was a skill in the Dawn's Wrath skill line which caused targets to miss attacks for four seconds, with a chance to be set off balance. Its Searing Light morph reduced the chance of missing attacks but dealt damage to affected targets, while the Blinding Flashes morph pulsed periodically, with each pulse causing nearby enemies to have 50% chance to miss and be set off balance. The ability was removed in Update 6 and replaced with Radiant Destruction.

Online:Tri Focus

Tri Focus gives a variety of benefits when performing a heavy attack, depending on the type of Destruction Staff you are using:

Patch Notes
Online:Destructive Touch

thumb|left|Flame Touch
thumb|left|Frost Touch
Destructive Touch deals magic damage and additional damage over time.
The Destructive Clench morph removes the damage over time but adds additional effects based on the staff type:
 Flame Clench knocks the target back.
 Frost Clench immobilizes the target and applies a taunt.
 Shock Clench deals splash damage to other nearby enemies.
Alternatively, the Destructive Reach morph allows the ability to be used at a greater distance, changing the name to:
 Flame Reach
 Frost Reach
 Shock Reach

 
Notes
Destructive Clench is a recommended morph for the Deathweaver build.
The Destructive Impact set from Dragonstar Arena will reduce the   cost and increase your spell power after casting.

Patch Notes
Online:Wall of Elements

Notes
The area of effect is a long rectangular path in front of the caster. This makes it particularly effective for melee-based enemies who tend to run directly at you. Casting in a narrow hallway or other constrained space is a good strategy, as there is almost no chance of them avoiding the affected area.
Only one Wall of Elements may be active at a time. Casting a second one will cause the first to expire early. This is particularly of note if using the Unstable Wall of Elements morph, as the explosion for the first casting will occur early if the spell is overridden in this way.
Elemental Blockade is a recommended morph for the Gleaming Champion and Beast Caller builds.
The Crushing Wall set from Maelstrom Arena will cause your light and heavy attacks to do more damage to enemies within the wall's area of effect.

Patch Notes
Online:Force Shock

Force Shock deals elemental damage from all three elements, and has a chance to apply an elemental status effect.  The Crushing Shock morph interrupts enemies who are casting a spell, putting them off-balance, while Force Pulse increases the damage and also damages up to two nearby enemies if they are currently afflicted with the Burning, Chilled, or Concussed status effects.
 
Notes
This attack counts as three separate simultaneous attacks, each of which has an individual chance of causing a Critical strike, so it pairs well with effects that trigger when dealing critical damage.
Force Pulse is a recommended morph for the Sorcerer Elemental Arcanist build.
The Concentrated Force set from Asylum Sanctorium will guarantee the status effects will be applied on every second cast.

Patch Notes
Online:Weakness to Elements

Weakness to Elements reduces an enemy's spell resistance.  It has no casting cost, and is instant, so the only thing you're giving up is a slot on your weapon bar, to make all of your attacks more effective.  The Elemental Susceptibility morph lasts for 1 minute and randomly applies Burning, Chilled, or Concussion every 6 seconds, while Elemental Drain restores your   to anyone who deals damage to the target.
 
Notes
Elemental Drain is a recommended morph for the Deathweaver build.
Casting Weakness to Elements or Elemental Drain on a target is not treated as an attack and will not trigger a response from the target.  Elemental Susceptibility is treated as an attack.
With Update 28, the amount of magicka returned by Minor Magickasteal was reduced from 300 to 168.

Or you can use the Ferocious Leap to give yourself some protection in the form of a Damage Shield after your leap, while also dealing Flame Damage.

Notes
Take Flight is a recommended morph for the Venomous Dragon build.
This is similar in both cost and effect to the Fighters Guild ultimate Dawnbreaker of Smiting, though Dragon Leap deals comparatively more damage and can be used to close the distance to an enemy.

Online:Flurry

Flurry batters an enemy with a series of five attacks, each dealing physical damage, with the last hit dealing three times the damage of the prevous.

The Rapid Strikes morph increases the damage for each hit, while the Bloodthirst morph restores your   on the last strike.

Notes
Bloodthirst was added in Update 10, replacing Blinding Flurry, which had a 7% chance with each hit to set the target off balance.

Stonefist deals physical damage and stuns enemies.  It is a good way to quickly disable a nearby opponent, either allowing you to deal with fewer melee attackers nearby, or to allow you to charge up a heavy attack or other ability as a follow-up.
