1. Training costs

FAQ §3-6 (lines 1171-1173). FAQ-sourced; ASM handler 0x9B48 / 0x9BCA (doc 28, §1.3) needs cost-formula trace to confirm.

Training cost = current_level × town_index × 50 gp

Town	Town index
Middlegate	1
Tundara	2
Sandsobar	2
Vulcania	4
Atlantium	5

Example: Training at Atlantium at level 5 costs 5 × 5 × 50 = 1,250 gp.

FAQ note: Atlantium gives almost double the hit points of Middlegate. Worth the extra cost — try to train there from as early as level 5.

2. Healing costs

FAQ §3-6 (line 1174). FAQ-sourced; ASM handler 0x1D208 (temple) — cost formula not yet traced.

Healing cost = current_level × town_index × 10 gp
             (×10 if character is dead)
             (×100 if character is eradicated)

Town indices same as training (Middlegate=1 … Atlantium=5).

Example: Resurrecting (dead) a level 10 character at Middlegate = 10 × 1 × 10 × 10 = 1,000 gp.

3. Magic item day-bonus cycle

FAQ §3-6 (lines 1181-1193). FAQ-sourced; ASM calendar mechanism not yet traced.

Magic item bonus (+N) shops stock items on a 30-day cycle. The bonus + value for items bought on day D:

D	+	D	+	D	+	D	+	D	+	D	+
1	1	6	1	11	1	16	1	21	1	26	1
2	0	7	0	12	0	17	0	22	0	27	0
3	1	8	1	13	1	18	1	23	1	28	1
4	2	9	2	14	3	19	4	24	5	29	5
5	0	10	0	15	0	20	1	25	0	30	*

Special milestone days:

• Day 30: +5
• Day 60: +6
• Day 90: +7
• Day 120: +8
• Day 150: +9
• Day 180: +12

FAQ note: the cycle resets modulo 30 for normal days; the milestone bonuses accumulate beyond day 30.

5. Bar drinks sub-game

FAQ §3-10-3 (lines 2061-2070). FAQ-sourced; in-game drink mechanic not traced in ASM.

Drinks are ordered at the bar. Each has a "sickness" threshold — drinking too many at once resets all stats.

Drink	Bonus (per successful drink after threshold)	Threshold
Orc Beer	+5 Might	After 1st
Straight Shot	+20 Accuracy	After 2nd
ID Elixir	+10 Personality	After 2nd
Academic Ale	+10 Intelligence	After 2nd
Rare Vintage	+3 levels	After 2nd
Mystic Brew	+1 spell level	After 4th

"If you get sick drinking a certain beverage, you have all stats reset." (FAQ line 2063.) Rare Vintage and Mystic Brew are extremely powerful; Rare Vintage +3 levels compounds if repeated.

6. Inter-town portal connections

FAQ §4-2 (lines 2178-2182). FAQ-sourced; portal selector bytes 0x64, 0x7E–0x83 documented in doc 28 §1.2.

From (coord)	Cost	Direction	To (coord)	Cost
Middlegate (0,5)	10 gp	↔	Sandsobar (6,1)	20 gp
Sandsobar (4,14)	50 gp	↔	Tundara (6,11)	10 gp

Vulcania (8,3)	100 gp	↔	Atlantium (3,0)	50 gp
Atlantium (12,0)	25 gp	→	Middlegate (0,5)	—

The Atlantium → Middlegate connection is one-way only (FAQ line 2184).

• From Middlegate portal, exit at Sandsobar: go 1S 1W, N several, 1W 1N.

7. Fly spell (S3-2) landing coordinates

FAQ §3-2-3 (lines 922-927). FAQ-sourced.

S3-2 Fly sends the party to a landing square in the chosen sector (A1–E4). Sectors are 5×4 (A–E = east/west columns, 1–4 = north/south rows).

	1	2	3	4

B	(14,3)	(13,7)	(15,3)	(13,15)

• Atlantium: A4 sector
• Tundara: A1 sector
• Vulcania: E1 sector
• Sandsobar: E4 sector
