Lots of speedruns out there, what about a midrun amirite
I guess some disclaimers I stopped at the end of base Rise, and only got playing Sunbreak after all the Title Updates dropped, so no I haven't done any Anamoly Investigations or dipped in any of the Augmenting because... they didn't seem like fun lol.
So it's really just me not wanting to engage with the game's previously available mechanics to finish this fight with just the mechanics available just by completing base Sunbreak raw and going straight into the other Urgent Quests without doing Anamolies.
For Gunlance I'd say I'm pretty spoiled by having a shield to block most of his attacks, as the only two absolutely unblockable attacks it seems are the lasers and the supernova.
