This is one of my first ASM modification that was implemented in RotDS redone now in an ASM file for greater customization. It allows the offering to strike between 1 and 4 times, each with 25% chance with default setting. To edit the chances of striking modify the three CMP values. The following setting as an example would allow 12.5% of 1 hit, 50% of 2 hits, 12.5% of 3 hits and the rest (25%) for 4 hits:

Code:

CMP #$20        ;12.5% will have branched at that point (32/256 = 12.5%)
BCC exit
CMP #$A0        ;62.5% will have branched at that point (0xA0 - 0x20 = 0x80 = 128/256 = 50%)
BCC twoExtra
CMP #$C0        ;75% will have branched at that point (0xC0 - 0xA0 = 0x20 = 32/256 = 12.5%)

For further customization, one or many extra CMP and branche(s) could allow a chance of 10 or 12 hits (5 or 6 without Genji Glove). Note that because how the code is structured, the number of hits in vanilla game is either 2 or 8 and one hand is not taken into account if no Genji Glove (thus 1 or 4 hits depending on offering). Because of that with both Offering and Genji Glove equipped, you will always strike 2, 4, 6 or 8 times.

Finally I added the option to remove the half damage property of Offering. Just comment and/or uncomment bottom code to enable or disable this option.

Edit: I use offset EE/AF01 for a lot of my ASM tweak. It is your responsability to change the org offset in order to relocate the code and manage properly your free space.  

Edit2: On a side note it happened twice during my testing that Terra (party leader with offering) would take the attack stance after selecting the Fight command but she would lose a turn, meaning she would not attack and keep the attack stance pose until I select the Fight command again and then she would attack normally. I wonder if that's a known bug or if I accidentally created that possibility but I'm not sure how I could have done that.

Edit3: Bug fixed (I think) and version 1.1 released.

Cool. The Offering could use some tweaking for sure, it's very overpowered. I might incorporate this into my own project.

If you disable half-damage modification for offering, I think it compensate for the randomness (having a moderated chance of 1 or 2 hits). Still you can play with odds which allow a nice balance in the end.

Edit: On a side note it happened twice during my testing that Terra (party leader with offering) would take the attack stance after selecting the Fight command but she would lose a turn, meaning she would not attack and keep the attack stance pose until I select the Fight command again and then she would attack normally. I wonder if that's a known bug or if I accidentally created that possibility but I'm not sure how I could have done that.

Edit2: Bug seems to be fixed.

I released an updated version (1.1) with the bug mentioned previously fixed. (probably >.>)

This patch has been updated to version 1.2. Basically I've done a default bank implementation ($C2 here) and a $EE (or other bank) implementation. I've also updated the readme and added more explanations.

The following patches (and threads) have also been updated to 1.1 for one or all reasons mentioned above:

Equipment Check Event Command
Cursed Tweak
Random Battle and Boss Themes

If you disable half-damage modification for offering, I think it compensate for the randomness (having a moderated chance of 1 or 2 hits).

Can you elaborate on what this means? So vanilla Offering does half-damage with each hit, and by disabling that property as well making it limited to 1 or 2 hits, you can make it more balanced?

Just trying to understand what would be an ideal setting for this tweak. I'm much interested in this, I was going to exclude Offering from my personal rom but this has potential to make it something that resembles fair.
