Tera - (TSHM) Timescape Hard Mode Nightmare Yana Gunner Pov

TSHM gunner yana final boss! My gear is full +12 schisma.
I believe at this time I already have 15 clears on gunner and 16 on lancer.
During this fight at 1:40 mark, I got a bit distracted from something near me and did recall a bit too late when I noticed the face changed lol. But glad I was able to do the next 2 mid just in time. I thought yana might get buff but that was a close one for that double mid rotate.
When yana says,"The power of the sun, dark or devil grows", usually this means he will either change the highlighted face on the wall or keep it the same. I also found when being in the cage, sometimes he may say this right before the mid donut. Good way to keep recall ready for that. Also if there are 2 vortex's inside..wait for others to leave, then leave with vortex, this way recall doesn't have to be used in case yana switches face.
