Demeter:

• Harpy: lifting enemy units into the air and sending them crashing to the ground
• Wither: unleashes a devastating wither upon a targeted area, drying out berries, plants, and trees, and transforming the terrain into barren wasteland where nothing can grow for a short period of time.

Pan:

• Lykaon: moves through the world disguised as a Villager until the moment it strikes with its true strength.
• Arcadian Meadow: creates a peaceful field that stops all attacks from units and buildings caught inside its glow

Hestia:

• Hamadryad: hides as a tree when idle, allowing for infiltration, scouting, and resource theft.
• Communal Hearth: offers defensive strength and resource bonuses, and it can convert enemy units to your side.

Persephone:

• Sirens: lure enemy troops with their haunting song, pulling them away from safety.
• Underworld Invasion: revives the last one hundred fallen units as spectral Eidolons under your control, at the cost of every Town Center you own.

Two separate disguise units is very interesting. I don't think we've had any of those before. Not even Shinobi, though in aoe4 Shinobi have a disguise ability.

A variant of locusts, and a localised variant of ceasefire. Interesting twists. I guess there are only so many ways to keep making unique god powers after a point.

I'm very curious about Communal Hearth. Defensive boost (like Sentinels?), extra resources (like Plenty Vault?) and concerts units (like Traitor?). It's pulling a lot of tasks for a Heroic Age power.

Underworld Invasion seems awesome. Kind of a variant of Ragnarok, I guess. Very interested to see how it plays out. That's a huge boost in population, at the cost of losing a heap of max pop, once your units die off.
