Why is it so difficult?

Hello, how should I understand why all these icons? and how to use them if there are only 3 slots for basic skills. They are also different colors. What is the difference is not clear. This is a very confusing option. And I think it should have been explained in more detail.

Hi, thank you for reaching out.

Colors stand for rarity so gold > purple > blue > green and you can assume that skill with better rarity will be more powerful.

However, a certain combination of skills can achieve 1 + 1 > 2 effects, for example, a skill that triggers a special effect when the target is stunned + a skill that causes stun can turn the tide of a battle.

So please give different skill combinations a try and choose the ones that fit your style.
