There's only one Health Berries and five Health+ berries.
I have a strategy that involves managing Mirage's HP for 9 level-ups. As far as I know, it's the most reliable way to do this. It's further back in this topic, but here's the process:
-Get Mirage's HP to 4716 through leveling up. Do not level up her HP skill! -Use one Health+ Berries on her. -Max out her HP skill. (You'll have enough points as long as you don't use them on anything else.) -Use the rest of the Health+ Berries. -Use the Health Berries. -Equip a weapon with 8 +20% HP factors, the Valkyrie Garb, and two refined Lunar Talismans.
This gives Mirage 77777 HP.
When I did this myself, this was her HP after every level-up:
2700 2900 3106 3316 3534 3760 3992 4230 4472 4716
I was able to get her as high as 4720 HP on the last level up, so you don't have to hit those values exactly.
