Goal of this Research

Identify which bytes are used during battle for HP Drain and MP Drain.

Direction to Take This Research

Create a new subroutine in the game to allow MP Drain digits to offer a new color, versus HP Drain.

Notes & Findings

There are 5 ways to drain MP in the game:

• !Dance Ability, with the Mystery Waltz
• !DragonSword Ability
• the Osmose (aka Aspir) spell
• the Osmose Sword attack
• and the Lilith Kiss Mix (either Maiden's Kiss + Ether or Maiden's Kiss + Elixir).

The two Mix recipes are almost certainly different in a lookup table, but it’s uncertain if they point to the same effect routine in the rom.

MysteryWaltz from Dance

Notes forthcoming

DragonSword

Here is a snapshot of the FFV rom while HP Drain is happening in battle from the DrgnSwd (Lance) Ability.

Bytes utilized for this effect are $110F08 - 110F17.
