Path of Ascension: Kalisthene

This fight is moderate in regards to difficulty.

Boss abilities
tethering spear. This will create a chain between you and the location it is cast you will see an grey swirly indicating this. It cannot be line of sighted this was patched. It will slow movement speed as you try to move away from it and will also drag you into it's AOE which does damage. It can be broken with Herald's footpads equipment. You can use pillars to avoid the dragging effect as they will hold you in place
Ascended Barrage. Kalisthene will fly up into the air and bombard the area you are in with spears. Avoid this at all cost as it is lethal.

For wisdom her new ability is a leap. She will fly up in the air and leap to your locaton which will show a swirl under your feet, simply move out of the way

Fight Strategy.
For this fight choose pelagos and as your equipment choose herald's footpads. I would still fight her near a pillar so that way you can use it to hold you in place and not have to worry about the dragging effect of the chains. I would break the chains honestly after the second chains. If she does do another chain before ascended barrage just move around avoiding the attack. I would recommend your shield from confront memories and dps boss when it is safe so you don't get drug into the tethering spear or hit by ascended barrage.

I also have a video guide on youtube just visit kor&dab productions. I recommend the loyalty video as the courage footage is out of date.

I'm sure this can be done - the videos are evidence of that. I, unfortunately, cannot get Kalisthene down to below about 75%. It seems a waste of time to me. I suppose I'll keep burning through the medallions until I run out, but that's about it.

Kalisthene hits hard, you don't. Kalisthene stops you avoiding damage by moving, and the cooldown on the footpads is 30 secs.

Don't use the footpads until she has the three chains on you. That way it will break all three at once.
