Awakened Vardorvis with Scythe and Voidwaker (

Struggled a bit with this one, but the final kill was pretty smooth, only using 4 anglerfish more or less.

Lessons learned:
1) Always prioritize skipping the axes. Taking a prayer hit can be fine, but an axe hit can be fatal, especially if you're trying to switch prayer and skip axes, but end up failing both. In the end, an axe skip is one click, switching prayers is often 3-4.
2) You sort of have more time than you think when switching prayers, and you can dodge an axe, then go back to switching prayers quite often if you're quick enough (see 2:33). You also don't have to immediately get ready to pray as soon as the head spawn, take a tick or two to just look around, or position yourself before praying.
3) Wait around 2 ticks after the spikes spawn above you, then just walk to another tile and back. This avoids all damage from it (seen at 2:52).
4) Voidwaker is fine to use anytime under 25% (or just above), and I wouldn't bother trying to spec when it's within KO range. It's usually better to just stay calm and let the scythe do the work, imo.
5) When he does the tendrils, right click him right before it, and click "Attack" as soon as the tendrils spawn, this'll make you attack during the screen overlay.
6) Always look in the oppsite corner whenever the axes spawn, as it'll tell you whether or not you can move back to the "safe" square straight away or if you need to dodge (and wait for) a potential second axe (or if you only need to reposition yourself to skip the opposite one).
