NOTE! This video is meant for those who are stuck at Chapter 7.5's boss! If you haven't reached at least Chapter 7, this will be a spoiler! Close this tab now unless you want to be spoiled!

Some people are having problems with this battle. So I decided to release this video to show you how to defeat The 'Extra' Boss of Revert, Ravier Connor.

Special Techs such as: 'Reserve Pool' and 'Andrographis Mist' are not used. OP Charms from Gumi's Exchange shop are not used. But you'll need the highest tier Special Gauntlets (Myrica, Lotus and Isoplexis) to pull it off.

Team used in this video:
Damien - Status Debuff
Lyeric - All-in-one Support - Taunt Guard, Bleed Out and Def Ignore
Athena - High damage, Bleed Out, Speed Debuff, AOE, High base speed
Isabel - Good RDF defense, High damage, AOE, Support ability
Gary - Guardian, Good Tank

For Gary, it is preferable that you outfit him with Speed and Status Protection in mind so he is able to out-speed Ravier and heal you in a pinch. (But I didn't do that in this video :p)

Alternative: Or if you want, you can consider using 'Righty Charm' which more or less converts Gary into a Ultimate Tank who can do very minimal damage.

Athena is extremely fragile with Maestro Charm, so unequip Maestro Charm and give her something else to bulk up her defenses. Isoplexis Gauntlet is recommended for soaking in some damage and the occasional lucky reflects. Given Ravier's high hit count abilities, it can happen fairly often.

For the first 2 stages: Save up your medicine that does not cause any side effect. So in first 2 stage, you can use Levoflovaxin or anything else. Save Vanconmyxin and Penicillin for later.

For Stage 3: Only use medicine such as Vanconmyxin and Penicillin as Drowsiness can cause Speed Drops. The final form of Ravier can easily sweep you in 2 consecutive turns - especially for some of its later attacks, so Speed Drops are the last thing you really need.

Make sure you prioritize Athena's Magnamic Dice for the speed debuff whenever possible.

If you can, try dealing Bleed out on Ravier to reduce his speed further. I was quite lucky in this video for Reploxion's Bleed Out to land twice, although the second one doesn't quite matter.

That's all! Good luck fighting against Ravier Connor!

Note: If you find it toooo hard, not to worry. You can wait till the sequel to come out and attempt it again. The Sequel's Ravier will be weaker compared to this and easier to defeat as it is required for story progression.

This is only for those who enjoyed the game and wanted a good turn-based RPG battle challenge :D
