Specific Character
Holiday
Ability
Crackshot
Issue
Crackshot deals technically does not deal Spirit damage. Instead if deals weapon damage based on Spirt Power. Despite this the item Mystic Burst will trigger with Crackshot if Holiday hits a headshot. Due to this interaction, it is reasonable to assume the item Tankbuster, the upgrade of Mystic burst would also trigger on Crackshot. This is not the case. Tankbuster does not trigger off Crackshot. And so the question is... why? is this intentional? A bug? Why is there an inconsistency when using these items on the damage ability.
Recreate
You can recreate this effect by playing Holiday equipping Mystic Burst, and shooting a target in the head with her weapon. What you should notice, assuming Crackshot is activated as an ability, is Mystic Burst activating upon holiday scoring a headshot. If you were to then upgrade Mystic burst to Tankbuster, what you should notice is that upon scoring a head shot Tankbuster does not activate.
Potential Fixes
I don't know if both or nether is supposed to work with Crackshot however from reading the items it would seem as if Tankbuster specifically works off spirit damage while Mystic Burst does not. Going forward I would suggest standardizing the items so they trigger off the same types of damage.
