Any sifu can offer some advice? I'm kinda lost. Been farming runes, then upgrade, then farm manas, then get new "seem to be good" monsters, then farm runes again, upgrade again, farm manas again orz.. endless cycle repeating.

I'm just blur on
1. how people awaken their monsters, or is it just wait for the correct element Cairos Dungeon and farm the hell out of it?
2. Then there's this evolve thing.... omfg, how do i evolve 4 stars monster T.T?? I mean, I need to train 4 of my trash mob to 4 star, for it to be fed to the one I want to evolve? and same for 5 star to 6 star? All mob max evolve at 6 stars? or some are limit to a max star rank. omg thinking of this already headache

As a beginner, should i just save my crystals and use it for energy points? First time I play a handheld game for so long, I couldn't stand the long wait from other similar games lol but this one got me hooked.

Finally just need some advice cause i really no clue whether I should feed/keep the monster i have .

Current main monster I use for dungeons/arena:
(None of my monster are awakened, all 4 star currently)
Dark Knight - wind | Succubus - fire | Epikion Priest - water | Bounty Hunter - water & fire | Vampire - fire
