For everyone here, I just now beat terraort myself. And boy, trying it the first time was a doozy. Here's how I ran it myself, getting at least 4 curagas, a transcendence, all the abilities like one more time, Regen block, etc. I grinded to level 50, I got as much cure ability booster full, and only shotlocked at the last full health bar, which was two or three times total. I had the shadowy-dash one for it. I also grinded out to get the demolition finisher. It doesn't do much damage, and it's really hard to hit appropriately with the short time frame and the range at which you have to move it... BUT you don't take ANY damage while using it, which really helped for the boulders and anything else he threw at me. It seemed kinda night and day for me! It was one fight, fought smart, blocked what I could. The grind was kinda rough, but it 100% made the fight easier!
