Combination skills were very difficult.
It didn't mean that if an Iron-eating Beast mastered Hardening and Thunder Palm at the same time, it could combine the two skills.
Even if it only used both Hardening and Thunder Palm on his palm at the same time, it wasn't that easy to do.
First, he had to consider whether his pet had the ability to use two skills at the same time. Second, he had to consider whether the energy of the two skills would conflict.
If he wanted to resolve these contradictions, there was no doubt that he had to solve them by increasing the proficiency of his skills.
Only when the proficiency of the skill was enough and the pet was extremely familiar with a certain skill could this skill be combined with other skills to be used.
The higher the skill proficiency, the higher the combination skill completion.
