I just downloaded the app, what should I do first??

It must be overwhelming since it's your first time. First, find a game you're interested in and enjoy it step by step. If you have any questions, feel free to ask anytime, and I'll be your guide.

ㅇNormal Difficulty ㅡ You can clear it by setting up 5 Clara Lv. 5s and 1 Freeze Lv. 1. - First, make Clara and Freeze Lv. 5. ㅇHard Difficulty ㅡ You can clear it by setting up Clara + Freeze and then Voodoo Priest and Ancient Blue Dragon in the remaining slots. - Voodoo Priest increases attack speed and critical hit chance. Level it up to 5. - Ancient Blue Dragon enhances attack power. Level it up to 5 as the 4th. ㅇHell Difficulty ㅡ I'll clear it someday, just keep collecting tickets and rolling. ㅇTip ㅡ Clearing Hard and Hell difficulty gives you 2 gacha tickets (Normal difficulty gives 1 ticket).
