I'm new here, I read some guides but still I've got some questions.
1. Does run through Tier 1 (using 100 energy) may provide more money then cost of 100 CE(+6k crowns)? When cost of 100 CE is lower (hours)?
2. What's best way to earn crowns with 2-stars EQ only?
3. Is it better to go solo or in party?
4. Does this equipment is good for swordmaster?
Wolver Coat and Cap, Calibur and Owlite Shield
5. What equipment should I get from 5-star stuff?
No T1 run gives enough cr to turn profit on a ce run. Unless you manage to get triple arenas in strat 2.
2* allows you to access rjp, royal jelly palace. That is the best place for crowns for T2 players.
Go in a party to learn how to deal with the stronger monsters.
The armour set is good for swordsmen.
5* equipments is determined by what you wish to do with that set. Look up Jdavis on the wiki. He has several guides on equipments for their purposes.
