New player here, got my archer to lvl 17 and I liked doing a lot of dungeons, just noticed that there are people with the same lvl or even when I was lvl 12 killing everything with one hit in the dugeons, like killing the bosses with 3 attack while I would take couple of minutes.

How are these people so strong? I don't think I skipped any quests and I'm using my level equips.

I got a merchant thing, like a pet you summon does some damage and then disapears. What are those? It sait it was 1/3 parts of a set. How do I get the others parts?

Will I get reset skills token later in the game or something like that because I think I made some mistakes? If not how hard is to get one without paying real money?

Can I buy cosmetics armor with gold and where?

Kind of dumb question but when I pray for my goddess I get prompt with a lot of choices, am I supposed to choose one of those or the game is showing all the things I'll be getting after I pray?
