Arcana's data tables (Arcana (USA), read from its bytes and our own disassembly of the code that reads them)

Rooks needs 20 experience to go from level 1 to 2 and 60,000 to go from 59 to 60. Salah, Darwin and Axs have Rooks' list word for word, Teefa's differs only below level 5, and the four spirits have lists of their own. Each of the nine characters (Rooks, Sylph, Dao, Marid, Efrite, Teefa, Salah, Darwin, Axs) has a list of 60 words, the experience from each level to the next: a level-up raises the level, then sets the experience still needed to the word at the new level in the character's list. No level-up happens at level 60, which is the cap. arcana-tables/experience

The word for level 0 (10 for Rooks) is never reached by a party member: characters join at Rooks' level, Salah at three below it but at least 1 ($07:B2AB-$B306). A character at level 60 has its experience still needed cleared ($07:B410-$B43B). The lists are 120 bytes apart from $05:A91A, in the order of the names table. Another script, at $05:801C-$8033, calls the same routines as experience ($07:B27A), row ($07:B335), then raise ($07:B256); which event runs it wasn't read.

Rooks starts at 150 HP and 30 MP with 10 in each stat, and (computed) his 60 rows sum to 748 HP, 246 MP, 205 Strength, 206 Endurance, 159 Intelligence and 157 Alertness. Each character has 60 rows of six words: maximum HP, maximum MP, Strength, Endurance, Intelligence and Alertness. Row 0 holds the starting values and every later row the gain on reaching that level: a level-up adds the row for the new level, holding HP and MP to 999 and the four stats to 255. A routine that rebuilds a character's figures clears them and adds every row from its level down to 0. arcana-tables/level-up-stats

The stat names come from the status screen's script, which prints the same four RAM words the rows feed in the same order. Row 1 is zero for every character but the three spirits Dao, Marid and Efrite, so a party member at level 1 has its starting values. The spirits follow Rooks' level. The rows are 720 bytes per character from $05:AD52. The rebuild routine ($07:B307) is called from $01:9131 and from scripts in bank 5 that weren't read. Another script, at $05:801C-$8033, calls experience ($07:B27A), row ($07:B335), then raise ($07:B256).

Each character has a list of 61 counts, one per level from 0 to 60, of the spells it learns on reaching that level, and a list of spell numbers in level order; the level-up routine counts the spells of the earlier levels to find where the new level's spells start. The nine lists hold 81 spells, never more than one at a level: Rooks 13, Sylph 7, Dao 7, Marid 8, Efrite 8, Teefa 12, Salah 13, Darwin 9, Axs 4. Rooks learns the four Call spells at levels 35 to 38, each spirit learns its element's Change Attr. spell first, and Axs learns four spells from level 15 to 30. arcana-tables/level-up-spells

Spell names are the spell table's ($05:E356, 22 bytes each, numbered from 1).

Arcana has 80 monsters. Rimsala's second form has the most HP, 3500; the 16 bosses are numbered 0 to 15, and 30 monsters can cast a spell. Each has a race and element word (the element in the high byte, 1 Wind, 2 Earth, 4 Water, 8 Fire, as the status screen names them, and no bit read as "Man"; the race bits in the low byte, which the race factor reads), Strength, Intelligence, Endurance and Alertness, three equipment numbers (weapon, armor, accessory), HP, experience, level and gold, which is added when the monster falls. The names pair with the stats in table order, as Data Crystal reads them; the boss numbers bear the pairing out, since the 16 numbered monsters are the named bosses, from Stone Guardian (0) to Rimsala's two forms (14 and 15), and the same 16 carry race bit $10. arcana-tables/monsters

Names come in the table's order; that monster n has the nth name is Data Crystal's reading, the stat tables' order is the loader's. The race bits: 1 on the undead (Undead, Skeleton, Bone, Jara, Ghost, Fult, Reach, Desurin, Raenon, Phantom), 2 on the four dragons, 4 on Ramia, Rilus, Aurane and Bali, 8 on Troll, Giant, the Cyclops and Minotaurus, and $10 on all 16 bosses. The weapon, armor and accessory numbers index monster equipment tables of their own. The word tables are at $05:C92D-$D0D4, gold at $05:CF95, the boss numbers at $05:D1E5 and the spells at $05:D235.

Arcana has 81 spells. Damage spells run from 10 power (Lightning 1, Smash 1, Water 1, Flame 1) to 200 (Attribute 11); the Call spells are 180 power at 40 MP; Heal 3 is 999. Attribute 1 to 10 carry two or three elements each and Attribute 11 all four. Each spell, numbered from 1, has a 21-letter name and a field in each of several tables: where it can be cast (1, 2 or 3), one target or all, accuracy, power, an element word whose top four bits are its elements (1 Wind, 2 Earth, 4 Water, 8 Fire), the MP cost and an effect class. arcana-tables/spells
