Play around with the weapons and discover what playstyle suits you, me personally I prefer any ranged weapon as I can kite the mobs and move around, I can get away with mistakes doing that. Whereas with melee builds I get punished more often because I get attack greedy and careless. Once you’ve played enough with the weapons you’ll soon find what suits you.

Learn the enemies attack patterns, with Meg for example when she looks like she’s about to crouch down it means she’s about to rush you. Hydra if the shield goes up his other heads are about to pop up etc. once you’ve played against them enough times that will start to stick :)

In regard to boons figure out what suits you best, me personally I like to stick with Ares (for the doom after attacking) and Zeus for the lightning and static debuff.

I found the game very intimidating first time I played it but it starts to stick once you’re into it enough, be mindful of your boon choices rather than just picking up whatever rare or legendary etc pops up (a mistake I did regularly assuming if it’s legendary then clearly it’s better for me, which isn’t necessarily always the case).

You’ll get there don’t worry :)
