Explanation of Configuration Settings for DPS: - 8 Curses applied to self for Self-Flagellation (in game this varies between 6-10 curses, regularly) - "Shock" effect is checked as stand-in for the Bonechill effect from Cold Snap, which otherwise wouldn't be counted (Frenzy charges from Cold Snap not included, as those wouldn't be active for a boss) ("Enemies killed recently" is left at 0 for Pursuit of Faith notable, as again that wouldn't be active for most bosses) Enemies are hit by Glacial Cascade typically at least twice (three times is possible on larger bosses) 469.425 per hit DPS * 2 hits per cast * 5 totems = 4.7M Sirus DPS (with flasks) Without Flasks = 3.7M DPS Instead, If assuming average 2.5 hits per cast: 5.9M Sirus DPS (with flasks) or 4.6M DPS without flasks. Upgrade: Watcher's Eye with Cold Penetration while affected by Hatred gets DPS even higher. Empower Level 4 instead of Added Cold is a bit more as well. Explanation of Leveling Trees: This all assumes you want to level with Glacial Cascade ASAP and are not using Holy Flame Totem past the first few levels. Early on, taking the Precision notable (Dexterity, Move Speed, Cast Speed) makes leveling much smoother. It's fine to take the nodes near Ancestral Bond but hold off on getting the keystone until your totems are stronger (either until they're in a 4-Link, or even after the first Labyrinth) Elemental Overload: a huge damage boost, but needs a Storm Brand setup to trigger it, so somewhat dependent on having the right links available.\ Around Act 6 (the 60 Points passive tree) there is a big re-spec which drops some damage nodes and changes pathing - on assumption you're getting damage from gear/jewels. If gear is bad and need damage from it, can delay this re-spec until later. Rush to fill out a cluster jewel as quickly as possible (this is show in the 80 Points tree). After that, go back to take all the life nodes and other jewel sockets.
