Linking & Link Mastery Skills

Thunder Breaker's attacks can link with one another to decrease the cast action delays between each skill. Successfully linking skills will also provide buffs such as
Lightning Elemental (1st Job) that provide provings a stacking %Ignore DEF and %Damage buff. In 3rd Job,
Link Mastery is unlocked that provides a stacking %Final Damage buff upon linking skills
Additionally, certain skills are labelled as 'Link Mastery' skills which are attacks that have cooldowns. Several of these skills consume stacks of
Lightning Elemental. Primarily, these skills are affected by the buff
Primal Bolt (Hyper Skill) which allows Link Mastery skills to not consume any
Lightning Elemental stacks and linking skills will reduce the cooldown of these skills. Below is a list of all Link Mastery skills:
Sea Wave - 2nd Job
Gale - 3rd Job
Shark Torpedo - 5th Job
Lightning God Spear Strike - 5th Job
