Season 6 data: monster stats of field monsters and Blood Castle 1–8 differ from the S6 server files #1518

Summary

I compared the Season 6 monster definitions of the OpenMU seed (src/Persistence/Initialization, current master)
with the monster tables of three Season 6-era server packages. Leaving resistances aside, 40 field monsters
(100 values) and the whole Blood Castle 1–8 table differ from a value on which all three packages agree.
I'd like to know whether you want these aligned before I prepare a PR.

Sources

• IGC Server Suite x6.0.0.1 — Data/Monster/Settings/MonsterList.xml
• Louis S6 emulator — Monster/Monster.txt (github OneAboveAlly/editmonstersetbase)
• emu-server (kyleruss) — Template/zGameServer/Data/Monster/Monster.xml; a repack of zTeam's Season 8 Episode 2,
  but for the classic monsters its table is identical to IGC (529 of 585 shared monsters match field by field)

I know CODING_RULES §9 says these are inspiration, not facts, and that emu-server is named there explicitly.
That is why the list below contains only values where all three agree with each other and OpenMU is the odd one out.
They may share an ancestor, so I don't claim three independent confirmations; but several entries look like plain typos
on our side (a digit too many), and some data is clearly a placeholder.

Out of scope

• Resistances — the seed maps the four resistance columns differently from the S6 GameServer
  (Ice, Poison, Lightning, Fire); that's a separate topic.
• Invasion monsters, Devil Square 7, Chaos Castle, Imperial Guardian — the emulators handle these partly through
  event configuration (e.g. Imperial Guardian monsters are level 1 / 500 HP in all three tables), so a table comparison
  says little.

Field monsters

Notable groups:

• Probable typos: Zombie Fighter (481) HP 5,000,000 vs 500,000; Blood Soldier 3 (184) defense rate 600 vs 60;
  Illusion of Kundun 4 (197) attack rate 7800 vs 780; Crypos (574) attack rate 11400 vs 1140.
• Elvenland: every monster has attack rate 10, and Hideous Rabbit (419) / Polluted Butterfly (421) look swapped.
• Kundun 7 (275): 140,000 HP vs 5,000,000, respawn 3 h vs 12 h — the boss is much weaker than in S6.
• Respawn times: Gorgon 10 s vs 150 s, Phoenix of Darkness 15 s vs 150 s, Yeti/Elite Yeti and Icarus monsters 3 s vs 10–30 s.
• Karutan: move/attack delays (monsters move about twice as fast as in S6).
• A few ±1–5 differences (Condra, Dreadfear, Ghost Napin, Necron …), listed for completeness.

40 monsters, 100 fields.

Gorgon (18), Yeti/Elite Yeti (19, 20) and the Icarus monsters (71–77) are defined in Version075/Version095d and inherited
by Season 6. I'd change them only for Season 6 (override in VersionSeasonSix) and leave 0.75/0.95d alone,
since these sources say nothing about those versions — the same approach as in PR 1481.

Blood Castle 1–8

OpenMU's Blood Castle monsters are shifted against S6: BC1–BC5 carry the stats of S6 BC3–BC7, BC7 carries S6 BC8,
and BC6 / BC8 match no S6 castle at all (BC8 has 3–6× the HP). As a result BC6 is also harder than BC7.
BC7/BC8 were already touched by FixBloodCastleMonsterAttributesUpdatePlugIn (my earlier change, which swapped BC7 and BC8);
this would supersede it with the full S6 table. All three sources agree on every value below.

Cells: OpenMU → **S6**; a single value means OpenMU already matches.

Proposal

1. Update the Season 6 seed values of the monsters above (field monsters and all of Blood Castle 1–8).
2. Add an optional update plugin for existing Season 6 databases (IsMandatory => false), so admins choose in the
   Updates page, like the spawn update of PR 1481.

Questions:

• Do you want this at all, given §9? If yes, field monsters and Blood Castle in one PR or two?
• Anything here you know to be intentional (e.g. faster respawns or the stronger BC8)?
