Day 1
We aim to get level 2 quickly by killing the camp that spawns near your drop location, after which we can go to one of 3 locations: We can either go to a Fort, an Encampment, or a Mineshaft, though I recommend going to the Mineshaft once you reach level 3-4.
We aim to kill a ton of creatures and get enough runes to reach level 8+.
While we cross the map, also keep in mind where the Churches and Scarabs are, for flask charges and a correct Talisman for your build.
Day 2
On Day 2, we want to start looking for either a Field Boss, Castle, or Ruin. We can also have a special event spawn where we want to head off to. If it's the Crater or Noklateo, you want to go there as soon as possible, because they tend to take the whole day. The other 2 can be done later on the day.
We also want to check up on the central castle, if Noklateo didn’t spawn, in case there are Crucible Knights there. If they are prioritizing this at all costs. Crucible Knights are fairly easy to kill, especially if you know how to parry, and they give a ton of runes.
Day 3
With this guide, we are fighting Fulghor, Champion of Nightglow, so next are some tips aimed at him specifically.
The only real danger from his 1st phase comes from his ground stab attack. This is where the lighting damage comes in because it's the ONLY way to interrupt this attack. If he gets this attack off, chaos ensues. A ton of holy pillars will strike from the ground, dealing a lot of damage while Fulghor, Champion of Nightglow chases you down. The rest of his attacks can be rolled pretty easily.
Phase 2 is where he kicks into overdrive, and we need to be careful. He becomes a lot more aggressive and has very wide attacks that can be hard to read, It's better to dodge out of them and run instead of risking being hit by them. The rest of the fight stays the same, as he will still try to do the stab attack from phase 1, which you can interrupt with lightning.
