Huh, I didn't even know it's possible to last until 2:40 and beyond with luck. Also nice progress on Helya! Hope it's doable before 8.2 or with Crucible gear?
(PS: a few things I forgot to say about Guarm just in case anyone else wants to try soloing it -
- It respawns in 10s, so you can hit it, save up to 5 stacks of icicles, and cast invisibility. Helps somewhat with the DPS.
- Don't Shimmer. Getting stunned is very bad for your DPS. Glacial Insulation/Blazing Soul's nice in that absorbs prevent spell pushback so they're useful beyond, well, not being Shimmer.)
