Attack Patterns

Above 50% HP

Volcano Crabs use all their skills almost equally, maybe being Power Attack and Flame Attack a bit less used than the other three. They use High Slash as a basic weak attack, High Flame as a stronger attack, and Flame Impulse as their most powerful attack, the other two skills are a way to deal more damage without using SP. When they run out of SP, they don't use neither High Flame nor Flame Impulse.

Below 50% HP

When Volcano Crabs' HP go below 50%, the odds of them using High Flame decrease, while the ones of them using Flame Impulse increase.
