Which god to study with Enki the Dark Priest?

[Goblin King]

Enki can devote himself to one god in his introduction: either Gro-goroth, Sylvian, All-merr or God of the Depths.

I wonder what's the optimal choice here?

Gro-goroth gives 5 spells, but they can be learnt through Blood Sacrifice or the Necronomicon. Eating flesh in the Mines can also max out its affinity.

Sylvan gives very useful healing spells, but its affinity can be raised by having sex in the bunny meadow.

All-mer should never be picked in the introduction, as its affinity can be maxed out easily by sacrificing the man on the statue on Floor 1.

God of Depths cannot be maxed otherwise, so it might be the best choice if you want to learn Flock of crows & Locust swarm. However the spells are not exactly spammable, with Needle Worm giving parasites, while Flock & Swarm cost a whooping 30 Mind.

God	Tier 1	Tier 2	Tier 3
Gro-goroth	Pyromancy trick , Blood golem	Necromancy , Hurting	Black Orb
Sylvian	Loving whispers , Pheromones	Healing whispers	N/A
Alll-mer	Blood portal	N/A	N/A
God of the Depths	Mastery over insects , Needleworm	Flock of crows , Locust swarm	N/A
