Lordash, you mentioned that only doors represented by sprites can be hopped over. Do you know if the blocked path leading to Verla is represented by sprites or background?

I haven't seen this happen with any other enemy, including the other bosses.
also i would liek a confrim deny about skiping over the heal boots gate using the money bag hop if possible not knowing is killing,( from on top of boots to over door?)
But something is off here... - You say that Silver golems die from 11 hits at 100 HP. According to the chart it's between 9-12, so that seems right. - You say that King Nole dies from 9 hits at 100 HP. According to the chart it's between 16-23, which can't be right. I also checked at 84 HP, the TAS takes 15 hits, but the chart says 28-40. My guess is that the listed Defense 31 and HP 200 for King Nole is incorrect. What should it be? Gola isn't listed at all, so his (her?) stats would also be nice.
EDIT: I made a chart of the number of hits it takes to kill an enemy given your HP. The top is the maximum number of hits, bottom is minimum (if you get 3/8 bonus damage on every strike). https://docs.google.com/spreadsheets/d/1bvb_4qVh4YpNMb2CeMxfYUeg-LSfKsTATB-Xr4lbQto/edit?usp=sharing It's a guess until I have answers to the questions above, in which stages of the calculation things are rounded down. It fits the numbers given for slimes and orcs at least. Names are according to the Japanese charts, I don't know the English names. Also, this: >BA (Base Attack) = Min(1,(HP-2*DS)*0.25) should probably be >BA (Base Attack) = Max(1,(HP-2*DS)*0.25)
Whooah, Thanks Lordash ! It's so amazing ! These informations are precious for TAS but also for speedrun haha :D However, it seems to me that when Ryle have 99HP (or 100, i forget) you kill all ennemies with one shot, even Gola.
How did you come by this info? Disassembling the ROM, testing and observing the RAM, something else?
Also, can BA and MA be fractional? (It looks like it.) Does the enemies keep track of fractional health, or is the whole damage floored to an integer before being applied?
How can there be a 1/96 chance of roundoff error? Isn't the same calculation performed the same way every time you attack?
I don't know Japaneese, but I worked out that the columns of numbers from left to right read the following: Attack Power, Defence Level, HP, Gold Drop.
The way the Defence level works is that it provides a minimum total HP that Nigel must have before his base attack does more than 1HP damage. Nigel's base attack will increase by 0.25HP for each level he has above the minimum total he needs for that class of enemy.
The minimum total HP is calculated from the defence score (DS) as follows:
HP = 2*DS + 4
Therefore it takes the following HP to reliably one hit kill an enemy (where EHP is the enemies' HP):
HP = 2*DS + 4*EHP
(If you want to always one-hit kill enemies, you will need to add one to the calculated HP level, as there is a 1/96 chance that there will be a roundoff error and your total attack will be ever-so-slightly less than the enemies' HP)
For example, minimum HP to one-hit kill various enemies:
White bubble (DS=3, HP=2): 2*3 + 4*2 = 14
Blue bubble (DS=3, HP=4): 2*3 + 4*4 = 22
Yellow orc (DS=5, HP=4): 2*5 + 4*4 = 26
Silver Golem (DS=60, HP=12): 2*60 + 4*12 = 168(!)
In addition to the above, there is a random chance that your attack will be boosted between 0 and 3/8 for each complete HP your base attack provides:
BA (Base Attack) = Max(1,(HP-2*DS)*0.25) (EDIT)
MA (Modified Attack) = BA + rnd*3/8*floor(BA)
Where rnd is a random number between 0 and 1, and floor() is the floor function (rounds down to the nearest whole number)
For the magic swords (on a full charge), another modifier is applied to the attack score:
FA (Final Attack) = MA * SM
Where SM (Sword Modifier) is given by the following:
Magic Sword: 1.75
Thunder Sword: 2.00
Ice Sword: 1.5
Gaia Sword: 1.25
Interestingly, the later swords have a lower damage modifier. I suppose this is to balance out the increased range of these swords.
You can see the enemies' HP by using a RAM viewer. Nigel's HP is stored as a 2-byte word at address 0xFF543E. Other enemies follow every 0x80 bytes (at addresses 0xFF54BE, 0xFF553E, 0xFF5BE, ...)
Sorry for the long post. I hope that made sense.
