This is a file of hex values relating to how combos are set up and used in
Phantasy Star IV. The data for how they are set up is quite different from the
information describing the actual ability.

Part 1) Byte descriptions [part1]

!1: This is the name that the game displays when the combo is activated. Only
  here as a reference, it is not stored with this data (but quite nearby).
  Check the offsets list if you want to find this text.

!2: This is the offset at which this data can be found.

Byte 1: The number of participants. 80 seems to indicate that a combo is
  order-sensitive.

Byte 2+: This is the index number of the techs and skills needed to activate
  the combo. Techs use their normal index number, and skills have 0x80 added to
  distinguish them. See section 3 for more information.

Part 2) Byte list [part2]

Part 4) Notes [part4]

-Did anyone ever know that about Destruct before? Order does matter, but enough
  permutations are listed such that order is irrelevant as long as Deban is
  cast first! Neat, eh?
  Update: I found it in the Phantasy Star Compendium translation. Oh well. It
  still didn't seem well-known.

-This section, despite the sensitivity and small number of combos available,
  has some really neat hacking potential. You could erase permutations of
  Destruct in order to add new ways to execute other combos. Or, hey, it would
  be quite easy to change it so that Triblaster will only work with high (Na-)
  level abilities (and yes, that WOULD make it stronger). If you were to remove
  Flaeli-potential from Firestorm, you could add 8 new ways to cause other
  combos.

-If you didn't know this before, there are two versions of Hewn, Flaeli and
  Tandle because Kyra is naturally better with magic than Rune. That's why some
  of the lists contain what seem to be redundancies.

-It would be nice to expand the combo lists a bit, (and the shop inventories)
  but I'm not sure where any available bytes are yet. I'll look into that in
  the distant future.

-I tried to make it so Gryz could use Silentwave. It worked just fine, except
  that Chaz showed up and cut the enemies instead of Gryz. It was pretty silly.
