Equipment
Venus Gospel, Wizard Bracelet, Ribbon
Materia
[Counter=Mime, Counter=Mime, Counter=Mime, Counter=Mime]
[Counter=Mime, Counter=Mime, Magic Counter=Restore(3), Magic Counter=Restore(1)]
All Lucky 7s yolo method requirements:
ATB on Wait
Battle Speed on Slow
Regen magic spell
Stop time at the right moment
Note: If you are using an action that auto-stops time like some limit breaks or counters for example; and you stop time manually before that action auto-stops it, you will want to stop time at 7776 HP because at next action regen will add +1HP (even if the time is stopped).
Fun Fact:
There is a way to change the 7777 damage into 9999 damage during the Lucky 7s. This requires Sneak Attack+Restore(3), Sneak Attack+Mime and the ATB on Wait.
You should start the battle with 7777 HP. The character will cast Regen with 80% chance. Enter in a menu (Limit, Magic...) and wait the end of the mimes. When you leave the menu, Regen will start and the character will continue the All Lucky 7s with normal damage (max 9999 HP). The number of such attacks depends on the number of mimes succeeded.
The number of 9999 damage attacks is : 1 + Number of Materias combos + Number of 7777 damage attacks BETWEEN these combos. Without Mime combos, this last number is 0. With Mime combos, your character will attack once between each Mime, so you will get a maximum of: Number of Materia attacks causing 9999 damage = 16 attacks. Therefore, leave the menu after the 48th attack and you'll do 533,280 damage.
