Champion Concept - Sidhecarr: Banshee from the Nook of the Marsh

I found an old piece of artwork from two years ago of a champion concept a friend asked me to draw. I drew the champ, outlined it in ink, and colored it in with colored pencils. Personally I do like the idea, but the original idea goes to jamesies789 for the concept. My DA link for the at is posted, with a concise description of him. The drawing is old and the picture doesn't really do it justice, but hopefully the idea gets across.

Sidhecarr's name is taken from Irish and in one form (bean sidhe) means "banshee." Essentially I see this champion as an AP utility mage/ support but with a little more damage than say Lissandra, but in the category of tankier mages like Vlad, Kassadin, and Morgana. Most people think of a Banshee as being female, but Sidhecarr is male, and I see him possibly being from the Shadow Isles with possibly a story of death and revival like Kalista's (although she is more a form of her old self.) His abilities aren't exactly set in stone (in fact there's not anything written down for some of them) so I'm going to attempt to write something that will support what he's meant to do. In fact I'm giving him a "Woman in Black" feel since he has something to do with marshes, and basing some of his abilities on Banshee lore. This is veeerrryyy tentative and tips or suggestions would be awesome.

• Ranged AP Mage

ABILITIES:

Passive: Morbid Foresight - Sidhecarr senses when an enemy champion is close to death and wails when they are nearby. This grants him a unique vision in which he can see a wavering of their soul in the fog of war around him.

• The movement of the enemy champion soul would be ethereal looking like tendrils of smoke moving through the fog of war
• ability name can be changed, but it is essentially supposed to reference a banshee's ability to foretell a death

Q: Song of Lament - Sidhecarr creates a shield-like aura around him (surprise! Banshee's Veil reference!) that gives him resistances and damages enemies in the aura. It will block the first ability that hits it, but this breaks the aura immediately. Auto attacks will not break the aura.

• Originally called "Piercing Scream" but there's already a reference to that in his R
• the aura damage would be minimal - think of Sunfire cape or Nautilus' on hit shield "poison" (I know it's not a poison, but I can't think of the term at the moment)
• and, hey, for gits and shiggles the ability could just be called "Banshee's Veil"

W: Children of the Marsh (can be changed since I know there are actual kids who play LoL) - Sidhecarr summons the spirits of children (or the dead) to reach out of the ground and root (or snare) a single target.

• originally this was set at 3 seconds, but very few champions are allowed to have that any more, so 1-2 will probably be fine for him
• the idea of the root or snare can also be taken out since he does get a fear and this ability can rather damage a champion instead. Ability could be cast in a line like Nocturne's Q and slow/damage an enemy champion who walks through the grabbing souls while it remains active on the ground

E: Familiar Form - (Activate) Sidhecarr takes on the form of a female banshee and has a set time in which to recast this ability. (Reactivate) Sidhecarr sings a siren-like lamentation towards an enemy champion, fearing them. (Sidhecarr maintains a female form while doing this and changes back after the fear wears off and ability goes on cooldown)

• reactivate would be a skill shot

R: Banshee's Wail - Sidhecarr become ethereal (untargetable as he moves to the enemy champion) and attaches himself to an enemy champion. The targeted champion deals reduced damage to Sidhecarr as he wails and drains their life force, healing him for a percentage drained. If the enemy champion is killed, Sidhecarr will knock back and deal damage to any enemy champions around him.

• Maybe not quite so big of a knock back like Gragas or Janna ult, but enough to displace the enemy team a bit
• can be a targeted ability

Debating on whether he should have health or mana cost abilites. I'm not good with stats or ratios or guessing what kind of range he should have on any of his abilities, so I welcome anyone else throwing that in there, but I know for a fact he'd probably have a higher base health than most mages. No lore yet. I can post that later once I figure it out. In the meantime, input from the community would be much welcomed, and I hope the idea is interesting.
