Would like to share some thoughts on a demigod I've been thinking about for some time.
Name: The Devourer(Other name suggestions welcome!)
Type: General
Appearence: Not quite sure about this one. Imagined a somewhat fat beast walking on two feet with a large tongue switching between hanging from its mouth and being curled up inside its mouth. Could be something like this:

(Picture of Cuchulainn from FFXII. This is only meant as a tool of inspiration.)
Summary: Is able to swallow minions to gain certain benifits on the battlefield, while digesting the enemy. Being able to swallow enemy minions and friendly minions grants an interesting and different use of a minion. This would also allow him to swallow his own minions, which could be something like a "Vitamin slug" or a "Booster leech". Booth of theese minions(ideas) could grant some special effect if swallowed by "The Devourer".
Abilities:
Swallow: Swallows a minion/demigod using X amount of time to digest it. (Digestion time depends on the health of the minion/demigod)
Vomit: Exhales a swallowed minion dealing damage to an area and grants damage over a set amount of time to the units hit by the initial attack.
Accelerated methabolism: Increase movement speed, but speeds up the digestion. (Can only be used while having swallowed a minion.)
Drool: Drenches an area drool dropping the movement speed and defense of the targeted units.
Multi stomach(passive): Allows "The Devourer" to swallow more than one minion at a time.
Mark of the tongue: Licks a targeted enemy with its tongue giving the enemy a mark, which add some bonus damage if the user attacks the marked enemy.
Belly drop(passive): Grants x amount of % to perform a special belly drop attack, which deals extra damage and stuns sorrounding units.
Long spit: Shoots a lob of spit, which is able to hit enemies from a distance, dealing a little damage.
Insta-morph: Completely digests a swallowed minion granting health and increase health regeneration for a set amount of time.
These are some of the initial ideas. Since I am not sure about amount of damage, time... I leave this one to some players, who may have a better understanding of how much boost or damage some abilities should grant. Should this turns out to be a great idea for a demigod, then I might post a more precise version of it, with actual times and percentages. But remember, I am always open to suggestions.
Background story:
As the clashes of the pantheon cries from the violent skies another demigod lies dormant in the moist pitchblack swamps. A battle only available to the descendants of the "The Progenitor", but even though the noises roam loud and clear to it.
Long before the struggle of the pantheon began, long before the human race was created, "The Progenitor" took notice of the first entities to walk a distant realm. These beings, created from the primordial soup, were the first beings to walk the earth. Despite their primitive behaviour, consisting of walking around and messing with their body fluids, he found a certain affection towards them. After all, he was the one who created them with the use of the primordial soup. Starting out as an experiment in the capabilities of his power to create life, he soon realized, that these creatures were no longer just an experiment to him.
Gaining humans emotions towards such simple creatures could never be tolerated in the realm of the gods, which forced him to shroud their realm and their existence from the remaining gods. And thus he continued for several years until a brilliant thought struck him. Executing his new plan was no easy task. Increasing their intelligence, making them into faithfull believers of the gods were certainly no easy task. But such a thought never struck him, and he started to further use his power to evolve them. And so he did.
Another year passed, the creatures evolved, becoming more intelligent, stronger and more dedicated to the god with each passing generation. But to him it was never enough, always a litlle flaw, always a bit weaker than what he had hoped for. Becoming more and more frustrated with his experiments he decided to use the primordial soup once more in an effort to make these creatures the ultimate worshippers. But despite his efforts, every newborn of the ultimate generation quicly passed away before ever reaching maturity, except one little child.
"The Progenitor" raised his arms in triumphant victory only to be shocked by what was about to happen. As the child reached maturity and continued to grow he started to wonder. The wondering soon stopped as the childs skin turned, his body deformed, a tail grew and his fomerly peacefull smile turned into a ferocious sadistic smile filled with hunger. "The Progenitor" could do nothing as his perfect creation swalloed, digested and corropted every single one of his tribemen turning them into slugs and leeches. And as the last one was swallowed "The Progenitor" soon realized, that with every consumed life the beast had gained strength making it a demigod. Such an abuse of power would never be tolerated among the other gods, therfore he decided to break the must important law of a god, to never act outside of the realm of the gods.
Standing before the beast he discovered, that he couldn't destroy without the other gods knowing, which forced him to throw it back to its place of origin, the primordial soup, where it would slumber for eternity. Millenias passed and the beast was forgotten by its own creator, but despite being a castaway it too was demigod and a descendant of "The Progenitor". And as the clashes of the pantheon raged, it too could hear the call of a new god. And despite the millenias passed, and the changed enviroment, it too rose from the swamp once again smiling its ferocious smile and become a god.
Hope it's not too similar to the unclean beast and hope you're gonna like it. And remember: FEEDBACK PLEASE!
