Choose skills

Skills can be freely selected by the player, but because of their freedom, there are difficulties in selecting them.

• Don't lose your means of attack.
  Defending and healing alone will not defeat the enemy.

• Have defense way.
  Unless you have enough attack power to defeat all enemies in one turn, defense and recovery skills are important to be able to withstand continuous enemy attacks.

• Have at least one skill with a low cooldown.
  Skills with a lot of cooldowns tend to be very powerful, so you tend to pick them, but after using all the skills, you will be completely defenseless until all the cooldowns are over. Also, it may be overkill and the small turn may not work. (It takes 5 to 10 turns to use 1 skill to deal with enemies with low HP, etc.)
