Favorite boons so far?

[Rum Tum Tugger]

Still haven't beat Chronos yet but I've been relying on Hephaestus a lot in my runs, the burst damage + Vent has been saving me over and over, and I'm finding that I'm not going for some of the gods I used a lot in the first game.

Demeter boons seems somewhat nerfed, Poseidon DEFINITELY got nerfed (used to love stacking splash + knockback + wall damage + etc, it was kind of broken lol) and I'm feeling out how to use Selene's Hexes still. I really like Morph, I've tried a few others but they just didn't seem to have the same potential for me in really tight situations.

Moon Water is my crutch for now.

As for boons, Hephaestus (and Artemis still) so far seem to be the best ones. After that, Hera seems to be quite potent (though I'm really disappointed by her lack of vengeful attitude when I spurn her in a Trial of the Gods — we're taking about Queen Hera, who was spurned all the time by her own husband ffs!).

My fave weapon is the axe so I'll give my fave boons for that.

Hera's Sworn strike (Not great w/ single strike hammer)
-Aphro Flutter Strike
-Apollo Nova Strike

Hammers. Lots of good ones, but the one listed here can drastically alter what boons you want to search for.
-Upgrade for attack to be a single strike (Not good w/ Hera link)

Other than that they are all great.

Sprint Boon are pretty helpful. Most a great, but these ones I like just a touch more.
-Hestia soot sprint
-Poseidon breaker sprint

Cast is very useful w/ axe so an AoE cast boon is very helpful.
-Hestia Smolder ring
-Poseidon Geyser ring
-Apollo Solar ring

Misc
-Hermes Swift strike, mean streak, midnight oil
-Poseidon Fluid gain

Zeus is powerful, but with the axe you need to almost just focus on him to get things going.

Hook Blades are pretty good. Didn't really use the throwing knives until I picked that upgrade. It rips through enemies and does backstab damage. I imagine it would stack well with scorch and hitch as well.
