Mutation's event 115 now fights Magus in field 3 and runs to its end. Block 22's entry type=7 code=2 makes ccBoss03 (bossFunc code 2, MUT gcmn 0x006192c0) with its twelve ccBoss03Leafs, and block 24's absent type=7 code=2 follows once the drained body dies and exits. The reference is docs/engine/boss-magus.md.

How it was taken apart

The 70 functions of boss03.cpp (0x0049da20-0x004a7974), the needle's and the thunder's Creates, and the three tables were lifted to a straight-line form and ported from it, each counter and float checked against the listings (with the post-increment compare of 272 in mind). The names and layouts are Infection's DWARF. Mutation's ccBoss03 is 16 bytes longer: four words at +0x52720 (stuck, the pushed count, act 9's stage effect, the regrow), with m_blurRad and all after it 16 bytes on. Mutation adds Move, act 8 (back to the centre when stuck) and act 9 (skill 250 under camera 3), and its Epitaph table has 14 (act 9) where Infection's casts 9.

The game's slips are kept. OnThinkRise counts its bursting leaves with a loop that never steps its pointer: leaf 0 twelve times, so skill 10's atk is 514 or 0. Act 9's ccItemSkillRequest flag is whatever a3 held (the harness measures 1). The laser's LockPlayer argument is Think's jump table address left in a1, so the chat stays open. m_dmgCount is 100 and nothing writes it, so the needle (act 31) never comes. The escape turns toward dirc.x, 0. Most acts clear moveVector with vf0, whose w of 1 Move adds to the place's w.

The shape of the port

piney_battle::boss::magus is the body (Class::Magus) and magus::leaf a leaf (Class::MagusLeaf); each leaf is a character of its own (AffectFunc::Boss, row 11), taken out of it for the body's frame as Kyvia's parts are. The five tables are the combat group's magus_* entries (data version 13). Camera 3's moves, the camera shake, the flashes, the SE notes and loops and Magus's pictures are new Outs; piney_world::combat::boss poses x31's body for the leaves' places (OBJ_ex31leafNN), and the field's effects draw a dying leaf's ring (AutoSamonRing, model 195) and the dust of a landing.

The drain's lost 21

Under the autopilot the drain brought the Epitaph but not its 4500 HP: Magus kept 30000, its gauge ran on, and cheat HP was off. The target menu's EntryAffect(13) waits in Boss::queued for the boss's frame while the world is paused, so the boss's affect type stayed 13, and the drain menu's 21 met EntryAffect's check on a drained foe and was lost. The game's bossAffectFunc runs Affect at once, and every class's Affect takes a 13 (leaving the type 0) unless the boss is held. The queue now does that to the type (boss::entry). Skeith and Innis go through the same menus; their menu tests stop at the Epitaph and do not look at the 21.

Checks

tools/test_battle_magus_rs.py (PINEY_VOLUME=mutation) builds the game's ccBoss03 with its leaves and runs Main natively against battle_probe's magus: acts, place, target, HP, gauge, clips, every own member of the body, the twelve shocks and each leaf, the effects' slots, the party, the calls, the menu and both generators, each frame. Cases mix hits on the body and the landed leaves, the gauge, the drain, pushes, missed beams and menu types. 120 cases (308,056 frames) agree; the body's acts 0, 4, 5, 7, 8, 9, 12, 13, 14, 16, 18, 20, 22 and 25-28 and the leaves' 0, 14, 19, 21 and 22 are reached. The effect lives (the wave's 45, the dead effect's 120, a leaf ring's 20) are the game's.

boss::magus::tests hold six cases; the session tests event_115_ends_with_magus (block 21 to the event's end) and magus_drained_through_the_menus (menu 66, now with the 4500 HP) pass.

Under the autopilot

PINEY_SURVEY_ONLY=115 PINEY_SURVEY_GOD=1 PINEY_SURVEY_FRAMES=200000 ends story 115: done; 8321 places; last: desktop - icon 1 - events phase 4. Field 13 at frame 145,250, the arena at 148,550, Kite's drain at 165,723, Magus dead by 172,000. The first run, before the owner's field 13 changes in the tree, stopped in field 13 (blocks 0x7dc7): the pilot never talked to block 13's six NPCs.

The pilot's real attacks hurt Magus, and they are physical. Its CHAT order is Skills!, since Magus's physical defence (2000) is under its magic defence (5000); the members cast only for a resistance under 100, and Magus's are 500 and 990. Kite's skills (page 0) go at the target menu's pick, which is a landed leaf while one is listed (the pilot's focus, the first part up), so he mostly kills leaves (29 in the diagnostic), which does not hurt the body. BlackRose's hits reach the body at a tenth (cheat HP): about 1100 in 28,000 frames, enough for its gauge to break, then Kite's drain. After the drain (4500 HP, cheat off) the party kills it in about 6300 frames. Without BlackRose (a start put straight at block 21) nothing hurts the body.
