New vaal gems

I think it would be nice if every gem had a vaal version, here are my ideas for new vaal gems:

All vaal curses: Can apply to curse immune targets and ignores enemy "curse resistance" (ignore the "x% Less Curse Effectiveness")

Vaal ball lightning: Fire x projectiles in every direction, the projectiles will return to the caster at the end of their range or when they hit an obstacle

Vaal contagion: the duration of contagion and associated degeneration effects (Essence Drain) are reset when spread (this may need a long sould gain prevention)

Vaal convocation: Recalls and restores all minions to full life (or maybe only restores)

Vaal dark pact: (self cast only) sacrifice all your energy shield and all but one life, removes all effects (buff and debuff) and charges affecting you, and makes you invulnerable for x.y seconds. During this time, all your minions (if you have any) will gain all the effects and charges that were affecting you, ignoring their remaining time (if a flask had 1 sec left, your minions will still be affected by it for the entire vaal dark pact duration)

Vaal discharge: Has no charge cost, and the damage is based of your max charges, instead of current charges, has 100% chance to freeze, shock and ignite

Vaal essence drain: Deals significantly more damage and pirces all targets

Vaal firestorm: Summon a meteor that deals the total damage of all flaming bolts (20 in total) in a much smaller area

Vaal freezing pulse: A pulse of frost dealing 0 damage, but freezing everything around the caster (including enemies immune to freeze)

Vaal frost wall: Creates a stationary proximity shield (something like zana's bubble, but blue)

Vaal frostbolt: Splits into 2 identical bolts each time it pierces an enemy

Vaal glacial Cascade: Summon a small glacial cascade that will follow the cursor for x seconds dealing cold damage over time to nerby enemies

Vaal elemental heralds: 100% chance to apply a strong elemental alignment

Vaal ice spear: Enemies hit recently will explode dealing x% of their max life as cold damage and launch x more (vaal) ice spears (allowing for a chain reaction)

Vaal incinerate: Creates a coppy of you that will use this skill (like vaal double strike, the clone should always be using incinerate with 8 stages)

Vaal Lightning warp v2: Creates a singularity at target location pulling in all enemies (like vaal cyclone). At the end of its duration, explodes and instantly kills all non unique enemies inside the singularity, and deals heavy damage to unique enemies (stunning them), also knocks back, stuns and damages nearby enemies. (This may be "a bit" op and could be balanced by forcing the caster to channel this ability, increasing its "kills zone" radius, pull strength and damage when it explodes)

Vaal magma Orb: Creates a small volcano, spitting out magma orbs in every direction, and burning all enemies standing close to it (burning ground)

Vaal orb of storms: Hits all enemies in the area (instead of one, and chaining to a few more) and grants allies in the area x life regeneration

Vaal purity of elements -> gluttony of elements, but only affects the caster (no party abuse)

Vaal shock nova: same effect as vaal ice nova

Which ones do you like/dislike and why?

Vaal essence drain would be the most op of all because at level 40 normal essence drain does around 6400 damage, so i say for all the op vaal abilites should have a large soul limit
