Demigod needs a lizard. like a chameleon.
Invisibility, making the lizard impossible to hit, but also cannot attack. skill increases allow movement, maxed allows a sneak attack. very little mana cost to begin, but becomes very high once maxed.
Regeneration, passive skill that decreases death penalty wait (passed what citadel can offer)
Spit, Cover an enemy Demigod in a huge gob of lung butter. interrupts and immobilizes them for some time, but protects them from attack. taking them out of a battle for some time until it wears off.
Scurry, A burst of speed on all four legs. Cannot attack. Skill increases allow it to become a charge attack, rushing through or pushing back.
Intimidate, uses flaps of scales to enlarge itself to scare enemy creeps into switching sides. and turning around. (not possible?)
Lay eggs, Tower minions that stay next to a tower and help defend from melee attacks, boost tower regeneration.
We also need a water god. waves travel across the map but within them lurk Leviathan
Foundation, aura ability that steadily decreases enemy tower hit points.
Dilute, aura ability that slows all units within, and slightly decreases enemy armor.
Wash, clear an ally status effects. increases attack speed.
Power of Leviathan, Transorm Ability, The serpent emerges from the waves (i see him as long as the rook is big, high attack power, but can be hit on the tail from far back) (must be skill points involved, the transformation could do an AoE attack.
Run off, area of effect attack, and stuns, combines with wash when maxed to increase creep attack speed
Coil attack, The serpent gathers up and springs out for burst damage and pursuit.
Flash, A bright flash reduces all Enemy Demigods Sight range to the size of a Bramble shield. including towers and creeps interrupts attack.
just some Demigod ideas, not complete, or in depth.
