Topic: Regen/Spirit Wave Command

[Deathlike2]

Healing done is 10... but I will look into see if that can be tweaked (and see if it based on something else).

Command is supposed to heal 8 times (I'll double check just to be sure).

In the SNES version, FuSoYa is "held up" while this command is executed. In the GBA version, FuSoYa is free to execute another turn while the command is in effect.

The command effect is not reflectable... AFAIK.

[Deathlike2]

The number of times of healing is not fixed. In fact, it is simply tied to the Agility, relative to the group.

Regen healing normally under my group: 10
Regen healing when FuSoYa under Haste: ~8
Regen healing when FuSoYa under Slow: 20
Regen healing when FuSoYa under Slowx2: 26
Regen healing when FuSoYa under Slowx3: 27

Slow has a greater impact on healing. If this suggests anything insane, give FuSoYa a Cursed Ring so he's stuck doing healing for longer periods of times.

I suspect this behavior is similar to FF4A.

This suggests Slow being very stackable.. Haste is relatively inconclusive at best.

[Deathlike2]

Regen healing can last forever if Stop has been casted on FuSoYa while on Regen Status. Regen's timer seems to be messed up under this, and FuSoYa then is allowed to input other commands under this instance.

Executing Regen again resets the timer.

This corresponds with the speed modifier. Quote taken from the Tower of Bab-il documents:

starts at 10. slow adds +08 (upper bound 20), haste adds -3 (lower bound 0C)

Well, Haste doesn't seem to have any impact.

Hermes Shoes and Haste are wierd though...

Haste has a value of 253, Hermes Shoes has a value of 248. It's still relatively inconclusive at best.

[Deathlike2]

Now that I think about it...

3 is the result of 256-253...

Which implies Hermes Shoes has a power of 256-248.. which implies it has a power of 8.

I'm trying to avoid discussing the ATB too much, but I'm working on updating some of the info.

[Phoenix]

The most significant bit on the speed is the sign of the number. So values above 0x80 are negative, hence the -3 and -8 of Haste and Hermes Shoes.

[Deathlike2]

Yay signed numbers.

Only causes more confusion at times...

[Phoenix]

I've finished looking into this subroutine, and have discovered the calculation for how long Regen lasts. It seems very complicated considering how little the command is used, and how little variation it results in. I believe the calculation is:

Code: [Select]

Timer = (value at A0089 - 0x80) x relative speed x speed modifier / 0x10
This timer counts down about two or three times every character (ally and enemy) turn. HP is restored every 6 clicks of the timer. Stop probably uses the same timer, which is why it restores FuSoYa's movements after it's used.

I've also found two ways to make this command more useful. The first is simply increasing the HP recovery. The data to change is at 1E5E9 (FF2us ROM with header) or 1E601 (FF4j ROM with header). This byte is 0x0A = 10 HP, so changing this to 0xFF = 255 HP. Unfortunately, you can't make it any higher than this, at least not that I could discover. The second way I thought would be useful is to let FuSoYa input commands again immediately (i.e. have no delay) and just restore 10 HP for the entire battle. To do this, change the data at 1E601 (FF4j: 1E619) to 01, and change the data at 1E60F (FF4j: 1E627) to 00. Naturally, you can combine these two fixes, but I think that makes it too powerful.

I'll be creating these patches later to put on Romhacking.net if you don't want to change the data yourself and can wait for the patch.

[Deathlike2]

I'd say doing both would be worthwhile.

My guess is that you can do both, but to a more limited extent.

Regen should heal (12?, 15?, 16?, 18?) 20 to 25 and not lock FuSoYa into a near-useless state. That's the best I can come up with w/o making it imbalanced.

Think of the healing in terms of the Medicine command and Pray command. It would be a far better than Medicine, but be at-par with the Pray command when Rosa has a maxed Will stat (and factor in that Pray is unreliable and a multitargeted Cure1 doesn't heal much late game). It's pretty solid a change IMO.

After seeing the command "lockup timer" change in FF4A, the command is just a "might as well waste FuSoYa's turn for free healing" (but that's because FuSoYa sucks). Increasing the healing without wasting too much time is a bad idea...

[Deathlike2]

Mega

The Stop timer bug is fixed in FF4A. It's great for FF4 though.

[Deathlike2]

 
The WSC port doesn't do the FF4A niceness of not locking FuSoYa into a coma-ish state... so it's more like the original.

Phoenix mentioned the Regen Subroutine a while back, but I thought toperhaps  show it in full...

Hmm, there is clearly something missing here, likely alot...

There is no explanation within how the game puts the 10 HP into well... HP, and if there 's a way to possibly modify that to say MP like TAY did.

[Deathlike2]

Phoenix IIRC wrote a hack for this command to change the healing value. I suggest you look into that @ RHDN.
