Final Fantasy III: Half Knife

The Offering relic is supposed to cut damage inflicted by weapons in half. While this is true in most cases, the ValiantKnife is an exception. The damage inflicted by the weapon itself is halved, but the bonus damage it inflicts, which is equal to the difference between the attacker's maximum HP and their current HP, is not. This patch makes sure the bonus damage is halved when Offering is equipped.

PURPOSE:
The Offering Relic allows you to use your weapon(s) four times to attack, at the cost of halving the damage inflicted. However, this isn't always the case. The ValiantKnife weapon has the ability to inflict additional damage equal to the difference between the attacker's current and max HP; while the main damage inflicted by the weapon is halved, this bonus isn't. This patch remedies that.

VERSION HISTORY:
v1.1 (February 25, 2018): Added an overflow check to the damage bonus algorithm. Also added GBA patches.

v1.0 (May 13, 2016): Initial release.
