'Blood Hero' spell requests

In my current project, Onslaught Arena, I have a hero called the Blood Shaman. As of now, I am stuck trying to come up with more interesting, unique, and fun spells for him. All my heroes have an innate ability, 3 normal abilities with 5 levels, and an ultimate with 3 levels

He is a healer class whose abilities revolve around 'blood'. His twist is that all his spells require his own life to cast.

Innate: Desperate Conservation. As a crucial entity to the survival of his allies, the blood shaman's intuitive magic will protect him. Activate to become invulnerable for 3 seconds. Attacks and spells that push the Blood Shaman towards his demise will automatically trigger this spell. 35 second CD.

Clot Wounds Immediately seals open wounds and stops bleeding. This effect is more effective the more wounded the target is. Cannot be cast on self.
[Level 1] - Heals 2 hit points per 1% life missing. Costs 50 health.
[Level 2] - Heals 4 hit points per 1% life missing. Costs 100 health.
[Level 3] - Heals 6 hit points per 1% life missing. Costs 150 health.
[Level 4] - Heals 8 hit points per 1% life missing. Costs 200 health.
[Level 5] - Heals 10 hit points per 1% life missing. Costs 250 health.

Crimson Renewal Thickens the blood of an ally or himself, healing over 10 seconds.

[Level 1] - Heals 150 life. Costs 100 life.
[Level 2] - Heals 225 life. Costs 150 life.
[Level 3] - Heals 300 life. Costs 200 life.
[Level 4] - Heals 375 life. Costs 250 life.
[Level 5] - Heals 450 life. Costs 300 life.

I have two other abilities worked out, but I do not like them and am having trouble coming up with good spell ideas. I find it difficult to come up with fun healing spells.

So I am requesting two spell ideas--one of them an ultimate. I am very good in GUI and rather weak in JASS, so nothing extremely complicated triggerwise please.

Any help is appreciated.

Blood Spike Causes this unit to lose up to 20% of it's health, but deal heavy damage to target unit. Will not damage to any lower than 5% health.
[Level 1] - For each 10 hit points lost in this way, deal 1 damage.
[Level 2] - For each 8 hit points lost in this way, deal 1 damage.
[Level 3] - For each 6 hit points lost in this way, deal 1 damage.
[Level 4] - For each 4 hit points lost in this way, deal 1 damage.
[Level 5] - For each 2 hit points lost in this way, deal 1 damage.

Burning Veins Boils target unit's blood, causing it to lose life relative to its regeneration and allows it to fail on spell casting.
Lasts 15 seconds.
[Level 1] - Loses life equal to regeneration, and 15% chance of countering a spell.
[Level 2] - Loses life equal to 2 times regeneration, and 30% chance of countering a spell.
[Level 3] - Loses life equal to 3 times regeneration, and 45% chance of countering a spell.
[Level 4] - Loses life equal to 4 times regeneration, and 60% chance of countering a spell.
[Level 5] - Loses life equal to 5 times regeneration, and 75% chance of countering a spell.

That is my contribution for now...

I wouldn't suggest you have more than one healing ability unless they're very different styles of spell. Heroes have a lot of things to do in a map and having eighteen different flavors of ketchup but no burger is still kinda... unfulfilling.

Blood Share - Picks 3 closest units and sets their life to a same % (the text need some rework - ( takes (% Life of Unit 1 + % Life of Unit 2 + % Life of Unit 3)/3 and sets the life of all units to that ... can be used to heal allies and to weaken foes )

@Panto
Creating a healing class that is fun to play is one of the most difficult gameplay aspects I have worked against. My current 'twist' on him is that each of his spells requires health to cast. Barring the creation of a 'one-trick-pony' is my current gameplay dilemma.

As far as the spells I have:
Desperate Conservation: I have replaced this with spirit link. The health cost of his spells will also be distributed by spirit link.
Clot Wounds: my attempt at making a heal with something slightly different to offer.
Crimson Renewal: unlike Clot Wounds, this can be cast on self. It doubles as a self-health regain due to its effeciencey relative to health cost. This means that you can use this to replenish your own life (same premise as a spell that restores more mana than it costs)

I found my other two spells boring, and--because I was having trouble making good spell ideas--came here

@sas_scorpion
I was thinking of something along those lines for an ultimate. Possibly a channel spell that takes X life from each enemy and redistributes it evenly.

As far as i have seen, everything is based on health. I mean, he is a blood hero but does ALL spells need to be blood-like? I think doing something else makes it more interesting, like the fact that he is a shaman, blood shaman, with like elemental spells. Just suggesting.

If it is a typical arena where you creep and there are duels every few minutes, perhaps a move that can help him creep easier?

Something like

Blood Heat

Channeling

Causes the enemies blood to circulate fast enough to burn the enemy and all nearby units (Like immolate) After 10 seconds of channeling, the unit explodes dealing fire damage to all enemies and allies around him.

For a final, can't think of a name/description, but how about a stampede style spell (Withought channeling) that heals allies and hurts enemies? Maybe have 2-3 dummy units cast it in different directions, so it doesn't seem linear.

@resolve
I named him "blood shaman" but only in the context of a tribal leader. His lore is a tribal caster that uses his own blood as payment for his spells. Think more Native-American shaman rather than strict WC3 shaman. I appreciate the suggestion, but elements (lightning, fire, earth) don't really fit with my vision of him

@Conquestor
Yes, it is a "creep arena". Blood heat sounds interesting. Fits the theme while not restricted to the class role.

That ultimate would be a great idea, but would have to be 100% triggered to heal allies. I could do something like that, but I can see it being alot of work (more so than I usually pour in). kudos for creative imagination though.

I appreciate the feedback guys.

Nope. Just make 2 stampede spells, one that targets enemies and one that targets allies. As long as both have the same missile effect, are cast from the same point, and cast at the same point instantaneously, it should look fine.

Hmmm, good thinking Pyro. I must get to work on that. *glee*

Won't it still spawn the stampede units in random areas?

You could however make the spell do 1 damage, and then either heal, or damage the unit through triggers.

I can't see how you're planning on detecting when that damage is done...

Pyro's idea is working like a charm. For those interested, the spell is done quite easily. Make two spells based on stampede. Make one for enemies, and one for friendlies. The only difference between these two spells is the enemy one stays the same (aside from any aesthetics you want to adjust), but the friendly one, is set to affect friendly instead of enemy, and in the damage field you set it to negative (CTRL + double click). Then set two seperate dummy casters to cast the enemy and friendly stampede (since putting both two spells based off the same one will only allow 1 to be cast) in a random direction.
