+
+This command will let you modify the caught ball of a Pokémon that is chosen by the Player.
+
+1. First, our scripting macro:
+
+```c
+    @ Changes the caught ball of a selected Pokémon
+    .macro setmonball ballId:req
+    special ChoosePartyMon
+    waitstate
+    setvar VAR_TEMP_1, \ballId
+    special SetMonBall
+    .endm
+```
+
+2. Next, our special function. You can add it to any .c file, although since it's meant to be used from the overworld, I suggest `src/field_specials.c` specifically.
+
+```c
+void SetMonBall(void)
+{
+    u8 ballId = VarGet(VAR_TEMP_1);
+    SetMonData(&gPlayerParty[gSpecialVar_0x8004], MON_DATA_POKEBALL, &ballId);
+}
+```
+
+To use it, simply type `setmonball` in your script followed by the desired Poké Ball Item ID. For example, `setmonball ITEM_PREMIER_BALL`.
