Finally did the do, beat Spire of Stars. Yay. Nice chill group with several others who hadn't completed it. The final actual kill of him was literally by the tiniest of hairs, barely got the last ball into him in time, and he was enraged, it was nuts, and there was mass confusion whether he was actually dead, but he was. Took like 3 hours total, but that's a first raid clear for ya.
Got the raid sidearm which is supposedly like a Kinetic last hope, and the raid Fusion which I think is good, but no luxurious toast or cape to get 385, bleh.
Nothing left to do now but get 385 before hiatus. May not even make that.
Checked raid report earlier, so lifetime I stand at officially 9 Leviathan clears, 5 Eater of Worlds Clears, and now 1 SOS clear.
Mind you I've transitioned away from raiding since it became possible to reach max light without it, that and I take long breaks from the game where I even uninstall it (so I wont be tempted to duck back in real quick). Or unless there's some reason to raid (like the new power system kind of requiring it to hit 385 in a timely manner). I pretty much clear each raid or lair once just to say I did. Beyond that is ad hoc.
