For anyone else reading! I figured out some major ones!!! Your 3 main skills that you should bind (you can bind the god skills to hotkeys by pressing 1 through 0 while hovering over them, same with potions) are
GASH, BLOODY FEAST, and CONVERSION.
GOD ENERGY REGENERATES EACH TIME YOU LAND AN ATTACK.
Gash works on anything with blood, is a 1 hit kill (over time) and gets you blood phials. Interact with an empty potion bottle and you can mix blood with any herb to get new potions. Bloody feast is a direct attack that, again, works on anything with blood, and gives you instantly about 100 health.
Conversion turns each status effect you are currently afflicted by into about 70 health each, and lowers all of the meters for them, including ones that haven't filled up.
between these three, your survivability skyrockets, and skills can be used very often.
After you get a few rosetta stones, you can identify stuff until you figure out the item Broken Minor Construct. For about 5 ancient scrap you can turn it into a deactivated minor construct, each of which sells for almost 2000.
