[ForgetTheUnknown]

(edit im combining my two separate spell suggestions into one)

Spell Name: Blade Toss
Spell Tree: Metal.
What it Does: 3 projectiles of swords that shoot towards the enemy, dealing damage. Chance to proc bleed (optional).
Visual: Three small sized swords shooting out, similar to mist shotgun perhaps.

Spell Name: Lance Charge
Spell Tree: Metal
What it does: A dash similar to dash strike, but low damage and could pierce dr.
Visual: manifests a temporary spear of metal and charges forward with a slash animation.

Spell Name: Sea of Blades (e.e see what I did there)
Spell Tree: metal
What it does: Casts an aoe with swords on the ground, dealing damage to anyone that step foot in them.
Visuals: A bunch of swords piercing the ground, cracking it. The swords are arrayed to match the appearance of a typical damage aoe.

Spell Name: Sword Barrage
Spell Tree: Metal
What does it Does: Basically light blades, but metal and same sprite as SoH.
Visual: Light blades but use the sprites used for SoH

Spell Name: Bladesinger
Spell Tree: Metal
What It Does: I suggest another master for Metal, but it gives ap/crit and with active that throws shrapnel similar to marksman but deals a bit more damage. 10% to proc bleed through armed too? sounds cool.
Visual: Ok, mini Swords with the appearance of the ones in SoH that surrounds player. Or daggers. These blades surround the player.
