Stellar Blade

When you defeat the Stalker in Matrix 11, you'll unlock EVE’s Burst Skills, which are super powerful moves that have their own separate gauge to expend. While the Beta bar will fill when you do and take damage, the Burst gauge will only fill when you Perfect Dodge.

So, in order to help you out there, invest in the Burst Energy Recharge I and II in the skill tree whenever you can. Reflex Boost will also make Perfect Dodge easier to perform, as will the Reflex-Exospine (tier 2 upgrade), which can be found early on in Matrix 11, inside the train carriage that charges at you down the hill. Those, as well as Burst Charge Gear and Burst Recovery Gear, will allow you to fill the Burst gauge much quicker.

Then, it’s a matter of using and the face button attacks to kill 50 enemies. We’d definitely suggest a fully maxed out Punishing Edge ( and ) as that will cause some serious damage. 

While the fully maxed out Punishing Edge will kill most minions, you might need to whittle some of the tougher enemy’s health bars down to around 30-50% if you want to instantly kill them, though.

As soon as you’ve defeated your 50th enemy with the Burst Skills, the ‘Relentless Destroyer’ trophy is all yours.
