I'm assuming you tested that infinite health so it doesn't work on other generals, these Konami hack-and-slash dynasty warriors samurai warriors warriors orochi games use the same write routine for all generals and possibly even the little guys. I'm kind of assuming you found a read operation that hopefully works only for your character. If you're going for that, I don't know if there are any 1 hit kill things in the game, but it is worth cranking the difficulty to the max and trying your code in 1 hit kill situations, because codes based on read operations run the risk of not adjusting health before the game gets to the point where it checks for 0 or less health which can allow 1 hit kills to still affect you. Some games throw in the 0 remaining health check into the same function that updates the health amount to the new lowered amount, and if this game does it'll see 0 before your read operation adjusts it above 0 causing death. Give it a check if you're able.
