Combo

Some skills specify a Combo type. There are three types:

[Summary]

Using a Combo Starter skill grants the Combo Link status.
The Combo Gauge appears above your head while Combo Link is active.
You can use a valid Combo Linker or Combo Ender skill before the gauge disappears.
Linkers and Enders gain Combo Bonus damage based on the gauge's fullness.
You can perform a Perfectly Timed combo by using a skill at 100% Combo Gauge. Perfect timing doubles your Combo Bonus damage and grants Power Boom.
- Combo Enders gain additional Combo Bonus damage equal to the total bonus accumulated during the current combo.

[Details]

Combo Bonus damage modifies the next skill's damage by +0.5% (*, unique) for every 5% Combo Gauge filled.
- Ex. At 55% Combo Gauge, you gain +5.5% Combo Bonus damage.
- Perfect timing doubles the Combo Bonus damage (+20% at full gauge).
There's a brief grace period after the gauge disappears during which Perfect Timing is still possible.
A combo ends if the gauge elapses, you use a non-combo skill, or you trigger a Combo Ender.
Auto attacks and auto spells do not interrupt combos.
Combo Enders always consume all remaining Spirit Spheres, even if fewer are required to cast the skill.

[Example]

Triple Attack (starter)
→ Chain Combo (linker used @ 95% gauge)
- Gains +9.5% bonus damage
  → Raging Thrust (linker used @ 100% gauge)
- Gains +20% bonus damage
  → Asura Strike (ender used @ 100% gauge)
- Gains +49.5% bonus damage (20+20+9.5).
  
  [More details]
By default, Triple Attack is the only Combo Starter in the game.
The Combo Gauge won't appear unless you know at least one valid skill to combo into.
Movement does not cancel combos.
Bonuses that require you to be 'In a Combo' work while Combo Link is active.
If your target dies mid-combo, you'll auto target a new enemy in range. This behavior can be changed under @config → Advanced Settings.
