Fathom

Moderate

Fathom’s disabled prototype is unusually explicit about ambush position: walls and ceilings support a harpoon perch, while concealed stillness changes the defensive state. Those details make the concept distinct, even though they do not establish a released hero or a final balance state.

OverviewHow to play

What the prototype shows

The spray builds weapon damage through contact with heroes, and the leap offers a separate landing attack. The harpoon connects that close-range pressure to a wall or ceiling route. Its interaction with invisibility suggests an ambush sequence, but the conditions for staying concealed must be read carefully rather than assumed to work during every action.

What remains unconfirmed

The charged spit also behaves differently when the hero is not attached to a wall. A future guide would need to verify the transition from perch to attack and back to safety. Until then, the page documents a positional prototype rather than promising a tested assassination combo.

Lore

A notorious monster of The Deep, Fathom enjoyed cultivating an aura of mystery and fear around him. He was content feasting on wayward sailors and demanding tithes from selkies, but then The Adversary came and ruined everything. After all, when it came to sowing terror, how could he compete with a genocidal force of nature? It wasn't fair. Something had to be done to save himself from fading into obscurity...and so he seeks to summon the Patrons to ensure that he will always be the apex predator of The Deep.
