Suggestion Runeblade/Runewraith Skills

I'm bored so I've been thinking of a few skills for T2 lvl 61.

Mirror Blade:
Description: Upon next attack a copy of the users blade is made (runes applied to the weapon at that time apply to this blade) and strikes the target for 50% of the original blades damage.
Looks: Have an invisible entity spawn 1 block from the target holding a sword and then dissapear after it attacks.
Cooldown: 25-30 seconds

Combustion Rune:
Description: Explodes on impact dealing 80 AOE damage.
Looks: Red / Orange firework explosion
Cooldown: 12-15 seconds

Lightning Rune:
Description: Strikes the target with lightning magic dealing 90 damage to the target and 30 AOE damage.
Looks: Lightning bolt
Cooldown: 12-15 seconds

Water Rune:
Description: Striked the target with the power of water dealing 70 damage and soaking the target for 8 seconds causing thunder based attacks to deal 25% more damage.
Looks: Blue particles
Cooldown: 12 seconds

Sword Beam:
Description: Shoots a beam of light from the users blade dealing 90 AOE damage (bonespear style)
Looks: Like bonespear but with light blue explosions rather than white
Cooldown: 12-15 seconds

Astral Blade:
Description: Strikes the target with the power of the stars dealing 160 damage and stunning the target for 0.5 to 1 second.
Looks: Light Blue firework explosion
Cooldown: 20-25 seconds

Just throwing some ideas out there. Tell me what you guys think!
(wasn't sure about mana use from each attack)

I like it! I also like the lightning rune one as well...

However, THIS caught my attention.

(But only at full health, right? Heh, Legend of Zelda references... But only because it's dangerous to go alone.)
But in all seriousness please put this in. Would it be an AoE or just a single target explosion that (looks like it) should hit more? *cough fireblast cough*
Regardless, I'm fairly certain that if this one would become a thing, I'd master runeblade and runewraith in a heartbeat, with boosts of course.

I was thinking AOE. I'll add that to the original post.
