Dusk Diver 2

MISSABLE

When you're in a Burst (see Transformation Sequence  above) and the Burst Gauge reaches 180% (the normal Burst's max), a new move called a "Burst Ultimate" becomes available. It's essentially a finisher move to your Burst ability. To activate it, press  +  again once you've reached 180%.

Each Character has their own Burst Ultimate Skill. To see their skill and read what it does, you can find the info in their Skill List. From the Menu, go to Battle Prep > Learn Skills > and scroll all the way to the bottom.


BURST ULTIMATE EX:
Not required for this or any other trophy but nevertheless important to know: for most of the game, on rare occasions, your Burst Ultimate actually has another level, "Burst Ultimate EX", which takes it up to 200%. This happens because of "Dual Burst", which only occurs when an enraged target enters a Break state, meaning this is only possible on "formidable enemies", as they're the only ones who have an enraged state. "Formidable enemies" generally means bosses.

• Enraged: An enemy becomes enraged once their health has dropped beyond a certain level; you'll know it as there's usually some animation, and they often become red. In this enraged state, their strength is increased.
• Break State: Once you've completely depleted the enemy's armor bar, they enter a "Break state", where they become stunned for a short while and a Break Strike ( + ) becomes available.

So, in other words, when you're up against a tough boss, if you get them into a Break state after they've entered an enraged state, your max Burst Gauge increases to 200%. If you reach 200%, press  +  again, and you'll perform a Burst Ultimate EX ability.

However, starting from Chapter 11, the Burst Gauge permanently increases to 200% and you will be able to enter Burst Ultimate EX the same as you would the normal Burst Ultimate. (See TV Taught Me How to Fight .)
