What system would be best for my setting? It's based on the idea of six major body fluids, each with a god associated with them. Each fluid also has a number of kinds of magics under its aegis, as well as manipulation of the other domains said gods have, with magic in general being closely related to the gods. The thing is, I need to fill out the domains for the gods, as well as some more of the associated non-elemental magics, and I'm having some trouble, particularly with Mucus. What I'm currently going with for each god is listed below, but some overlap could work, so if you have some good reasoning for why some domain/magic would work under another element as well, I'm all ears.
In addition to the main fluids, there's also a corruptive sweat that can both curse others and twist the other elements, bending them to one's will unnaturally, with the Perspiration associated with it viewing creation as a mistake and wanting to return everything to the sweaty wasteland.
Ejaculation has Light, Chaos, Magic, The Sky, The Ocean, and Creation as subdomains. It's associated magics include Time magics, summoning, and "buff" type spells.
Hemorrhage has Darkness, Order, The Forge, and Destruction. Its associated magics include Space/Teleportation magic, banishments, and "debuff" type spells that could drain a foe of energy.
Regurgitation has Life, Fertility, and Death. It's associations are with plant magic, communing with the dead, and wards.
Congestion has Truth and Lies. It's associations are scrying, along with summoning and dispelling illusions.
Lacrimation has The Moon, Freedom, Death, and The Hunt. It's associations are with Potions, animating the dead, and Healing.
Urination has The Morning Star, War, Wealth, and Rebirth. It's associations are with magic that deals with emotions.
