edited repost of my abitity merging idea.

Sparxlost

i imagine a place you can go to look at all the abilities you have unlocked and merge them to create new ones... some skills would be able to be obtained by multiple classes (smite skill can be used by borh templars and sorcs and maybe even other classes in the future like necromancers)
rules...
ultimate abilities cant be used to craft new abilities
merge a morphed class skill with a base non class skill to make a new skill...
there are limited options for crafting new abilities...
once two abilities are merged they are disabled and cant be used for crafting other skills until they are separated.
always uses the morph of the class skill you have chosen to determine what skills can be merged as well as what resource is used to cast...
the non class skill will always be merged as its unmorphed form and will do what it does or change the effect of the class spell in a unique way..
Examples...

dragonknights
noxious breath, whirlind: stam cost does whirling blades with the green nox fire breath effect on it to reduce enemy resistance and add DOT
(same idea with flame breath: mag cost fire effect causing burning)

green dragon blood, evasion: Heals, gain major fortitude and endurance, gain minor vitality, reduces damage from area of effect attacks as well as reducing the range you can be detected while you are crouch stealthed.

volatile armor, ice impulse: mag cost volatile armor but frosty blue shoots out ice spikes to slow and apply brittle to enemies
hardened armor, ice wall of elements: icy armor casts wall of elements shield on you and nearby allies

stone giant, lightning destructive touch: stamina cost throw lightning rocks at the enemy to apply stagger and if the rock connects it explodes in aoe for less damage but applies lightning status effect to the enemies hit by the aoe (the original target isnt effected by the debuff from the aoe as they will already be afflicted with stagger)

templars
blazing spear/lightning wall of elements: (smite) summon a bolt of lightning which leaves damaging waves of lightning on the ground. synergy does burst damage and can be activate by the caster..

Living dark, evasion: increases the duration changes the effect look, heals you when you take damage and snares attacker, reduces damage from area of effect attacks as well as reducing the range you can be detected while you are crouch stealthed.

ritual of retribution/lightning wall of elements: slight amount of of golden lightning flickers across the cleansing aoe
afflicting lightning damage on foes with increasing intensity as well as applying status effect..

sorcerer

Defensive rune, evasion: next enemy to attack you is imprisoned, reduces damage from area of effect attacks as well as reducing the range you can be detected while you are crouch stealthed.

crystal frags, fire destructive touch: instant cast a fireball for slightly less damage
crystal weapon, blade cloak: cloak yourself in crystals which deal physical damage every x seconds and reduces targets armor by 1000 for 5 seconds. also reduces cost of next non-ult ability by 10% (no longer buffs light and heavy attacks)

twilight matriarch, vigor: summonable harpy deals physical damage and constantly emits a small amount heal in an area around it. ability recast is a burst heal that which triggers a cooldown for all of the harpy's healing for a time..

restraining prison, balance: send out magic to apply vitality to allies hit.. reduces cost of next magicka ability and if no one is hit then the cost is refunded..
