SO,
FINALLY managed to have some time left for an event 
Plus, trying to use same particles and color for the effect
To-Do list of the heal effect:
[ ] Charge
[ ] Hit
[ ] Heal zone
[ ] Dissapear
Of course going to post things, but im going to sketch a bit.
FINAL ENTRY (Gif and Video):

made the heart on 3ds max
So, made a toon lightning for the heart, and implemented too a simple noise dissolve to make the heart appear over time. Started with charge particles, and made heart animation still a lot left but its something 
Made a circle, and a placeholder impact particles.
Started adding some glow too, so the heart shader has now fresnel
Texture made with Polygon shapes on photoshop, 5 sides in and out, then some circles and 2 triangles to make the stars
Gotta edit the particles sheet too (for that i made a sheet with a plus and a circle
GLOWY
I think that the “Charge” part is almost done, plus, added a sphere “explosion” to add more sensastion of hit. Some particles share that work with limited velocity over time.
AND, made some room to the heal over time.
Changed environment a bit, addeda glowing heart with rays and some particles for the healing area that fits with the dissappearing part
Gonna do some final touches before saying its a final entry
Added some final touches.
Of course there is always room to improve, but ill leave it here.
Have a good dev!
