Giving Umaro's attacks to another character

Can you turn Umaro's attacks into weapons that do that desired effect?

Probably yes, but you need good asm skills.

You can try to change the special effects of weapons by assembler code. The $11A9 variable triggers an adjustment function based on the C2/42E1 and C2/3DCD tables. You can change a pointer to a new function and try to recycle Umaro's functions in it. I believe the original functions needs adjustments and probably shouldn't be called directly.

You probably need to erase one of the weapons special effects and replace it for the new one. The pointers for the $11A9 tables are:

Code:

$11A9 value             $42E1 table     $3DCD table
00 ????                 -----           -----       
02 ????                 -----           -----       
04 atma weapon          $4044           -----
06 random kill          -----           $3D43
08 2x damage to humans  -----           38F2
0A drainer              $3F73           -----
0C soul sabre           $3F6E           -----
0E rune sword           $3F22           -----
10 random throw         -----           38FE
12 dice                 $4158           -----
14 valinat knife        $3F89           -----
16 wind slash           $3F9F           -----
18 heal rod             $3F7E           -----
1A slice effect         -----           388D
1C ogre onix            $3ECA           -----
1E rune sword           $3F50           -----

You should also check the C2/163B routine. It determinates what kind of attack Umaro will use. The code executes one of the four Umaro's moves at the C2/1676 table.

Code:

C2/1676: 92 16     (Throw character)
C2/1678: 0D 17     (Storm)
C2/167A: 7E 16     (Charge)
C2/167C: 1B 16     (Normal attack)
