Luminous Avenger iX Trophy in Gunvolt Chronicles: Luminous Avenger iX

This is the most challenging trophy in the game but with the right preparation this isn't too difficult. The Boss Rush cannot be cleared until it is unlocked. To unlock the Boss Rush, first you must beat the game. After that, reload your save file and you will see additional Special Missions in the mission menu. There are 6 in total, and they are pretty easy. They are short snippets of stages with a few more enemies (nothing too challenging) and then one of the 6 Adept bosses at the end. The bosses themselves are powered up a bit and no longer seem to have any weaknesses to EX Weapons. Clear all 6 missions and the Boss Rush will be added to the mission list.

You definitely want OD Auto-Recover and Regenerator for this. Focus on building your Kudos to 1000 as soon as possible so that you can keep your HP with Overdrive (Lola in diva form) and the Regenerator upgrade. Extra Bullits and Extender really help too.

You will face bosses in this order: Rebellio, Stella, Crimm, Isola, Bakto, Dystnine, Giga-Lola, Blade, The Butterfly Effect and then both encounters with the final boss. Keep your HP and Overdrive as long as you can. Use the SP skill only if you are on the verge of death, as this will heal you but remove your Overdrive. Providing Overdrive is active, you can fully heal before every battle as well as heal during battle which is very useful.

You can use checkpoints every few bosses, if you wish but if you're confident in your skills and you have the Overdrive activated, I'd skip it. The Overdrive is much more useful to you and rebuilding Kudos can be costly, especially since using EX Weapons doesn’t build Kudos.

Of particular note is the second form of the final boss. They squeezed in a tad bit of story into the rush. The last boss is powered up a bit. Its attacks are stronger and have more screen coverage. However, if you have Overdrive with Regenerator and are consistently locked on and attacking you should be ok.

The trophy will pop when you return to the base of operations. You won't get any in game rewards for your hard work but you will get a trophy.
