Originally was going to just fight it head-on with the other FOEs, but that's not a great idea while not using any grimoires... so I just took the fast path to fight it. You are able to get pre-emptive if you do a little more, but given that Turn 1 is fixed to be Thunderwing, it's really one action difference with Volt Wall, so I didn't do it here.
Thunderwing is used on Turn 1, and then potentially every 3 turns. Thunderwing is not guaranteed but it will not be used in shorter intervals. Iwaoropenelep has HP threshold-based moves and changes in pattern, but Thunderwing takes precedence over those. The ones I am gauging here are Chaosbringer (75% ish) and Wind Breath (50%). I need to refresh buff once so I use that to control the threshold a little.
I kinda forgot that Highlander did not have panic nullification accessory. That is something I could have easily done and would have made things safer, but I got the kill so meh.
Vulcan Stance still putting in solid work. Set-up taking extra turns and actions is a little annoying, but it's definitely doing its job. Also uh, panic accessory is probably a safer option because Vulcan Stance will make panic attack target-all on the party. Not the situation you want to be in.
