Title: HP% Spells
Post by: Entroper on March 08, 2008, 09:29:03 PM
Spells like Self-Destruct make perfect sense.  The spell power is 1, the HP% parameter (Column E in my table) is 100.  It does 100% of your current HP in damage to the target.  What does it mean for spells that have spell power greater than 1?  There are an awful lot of spells that are hp-based that I didn't know about, and it doesn't seem like the algorithm is as straightforward for these.

I was planning to write about this, but there's a basic formula.

There's a Spell Power stat and an HP Factor Stat (whatever you think of calling it).

When both are multiplied, they equal 100%, although I think that's not entirely required.

Hold on.. revising algo first...

For the SNES+GBA version, it is simply this:

Damage = maxHP/ Spell Power * Elemental Multiplier

Elemental Multipliers:
Weak vs Element = 2
Strong vs Elemental = 1/2

If you absorb this element and are using the SNES version, then apply against my magic damage algo.
If you absorb this element and are using the GBA version:
If single targeted, use my magic damage algo, but substitute the second value in the list as the spell power.
If multitargeted, simply invert the damage by multiplying by -1.

I've posted a thread to keep the algo at the top - http://slickproductions.org/forum/index.php?topic=448.0

Those are my current findings.. but that's primarily because there aren't many single targeted HP based elemental attacks.

Only vaguely on-topic, but are there any attacks beyond that one of the Dark Dragon which deal damage based on the HP of the target (with no variation to boot)?

(Forget the name, 25% of max HP. Which made it extremely overpowered for a Yang solo …)

Probably more than you'd think:

Maser: 1/10
Beam: 1/10
Fire: 1/5
Blaze: 1/4
Blitz: 1/2
Thunder: 1/4
D.Breath: 1/4
Big Wave: 1/4

Fire and Blitz are the enemy skills, not the spells you can cast.

Attacks based on the target's HP has never had any variation... except when absorbed in FF4A.

Thanks, DB! That really was more than I’d have thought. (“Fire” and “Blitz” are examples of bad localisation, anyway. :P)
