I found this page written by Philip
And he updated this page December 19 2021.
He explains all the basics in evertale and you guys should check it out. It's quite detailed and compact explanation. Hope it helps with your game!
Also wanna show you guys my progress I concentrate on one SSR character Astrid and one SSR weapon Dragonfury with maxed out awakening. I manage to go really far just because of one overpowered character.
Keep in mind that SSR characters and weapons max level is 200 mine is still a long way to go. Also I'm a free player haven't spend anything on this game yet.
The best tips I can give is keep your Soul Stones until it reach 1000 before you use it because it will guarantee you SR or SSR quality characters or weapons. Find a SSR character of your favourite and finish it hope you can get the maxed out awakening. I couldn't get any Astrid duplicate but I'll keep trying wish me luck.
