Hey everyone! I just finished a pretty challenging part of Endfield, and wanted to share my experience and tips, especially for those of you tackling the Bonecrusher Clan Investigation and struggling with the Aer-Ignis boss fight. First off, the Bonecrusher Clan Investigation itself can be a bit tricky to navigate. When I first started, I wasn't entirely sure where to find all the crucial intel. My advice is to thoroughly explore every corner of the designated investigation zones. Don't rush through; sometimes the key intel isn't directly on the main path. Look for hidden terminals, overlooked documents, or even subtle environmental clues. I remember feeling like "The starlight fades... all things return to one place" – a quote I saw somewhere – really set the mood for uncovering the clan's dark secrets. Persistence is key here, as you piece together the story and objectives. Now, onto the main event for many: Defeating Aer-Ignis at Lv.50. This boss was a significant hurdle for me, and when I saw "エアアイグニスを倒す" (Defeat Aer-Ignis) pop up, I knew I was in for a fight. The most crucial mechanic to understand is the "プロセス·冷起動" (Cold Start Process). This isn't just flavor text; it's a critical phase where Aer-Ignis becomes vulnerable or performs powerful attacks. During its Cold Start Process, pay close attention to its attack patterns. I found that having operators with good energy regeneration or crowd control was essential to either burst it down quickly during its vulnerable state or interrupt its more dangerous abilities. For my team composition against this Level 50 threat, I focused on a balanced setup: a strong defender to tank some hits, two reliable DPS operators (one physical, one arts to cover resistances), and a healer. Positioning is absolutely vital. Aer-Ignis has some wide-reaching attacks, so keeping your squishier operators out of harm's way is a must. I vividly recall a moment where I heard "That voice... the deadline is now, I have to overcome it" in my head as I was desperately trying to dodge a massive AoE attack. It felt like the clock was ticking, and I really had to step up my game. Don't forget to utilize your operator skills effectively! Saving burst skills for when Aer-Ignis is stunned or during its Cold Start Process can dramatically reduce the fight's duration. Also, make sure your gear is upgraded, and your operators' levels are competitive with the Lv.50 recommendation. If you're finding it too hard, try tweaking your operator module setups or even practicing dodging its specific attacks. It took me a few tries, but eventually, I found the rhythm and managed to take it down. The feeling of accomplishment after finally seeing "エアアイグニスを倒す" completed was incredible! I hope these personal insights help you through the Bonecrusher Clan Investigation and defeat Aer-Ignis. Good luck, and happy gaming!
