This tutorial will remove the stat boosts given from badges and replace them with increasing obedience levels for each badge.

3. [Update obedience levels](#3-update-obedience-levels)
## 1. Remove badge boosts from damage calculations
First, we need to remove the badge boost function and every place that calls the badge boost function. That way, badges will not affect how damage is calculated.
First, let's remove the function. Edit [src/pokemon.c](../blob/master/src/pokemon.c):
```diff
-static bool8 ShouldGetStatBadgeBoost(u16 flagId, u8 battlerId);
```
```diff
-static bool8 ShouldGetStatBadgeBoost(u16 badgeFlag, u8 battlerId)
-{
- if (gBattleTypeFlags & (BATTLE_TYPE_LINK | BATTLE_TYPE_EREADER_TRAINER | BATTLE_TYPE_x2000000 | BATTLE_TYPE_FRONTIER))
- return FALSE;
- else if (GetBattlerSide(battlerId) != B_SIDE_PLAYER)
- return FALSE;
- else if (gBattleTypeFlags & BATTLE_TYPE_TRAINER && gTrainerBattleOpponent_A == TRAINER_SECRET_BASE)
- return FALSE;
- else if (FlagGet(badgeFlag))
- return TRUE;
- else
- return FALSE;
-}
```
Now, we need to remove all the calls to the function. The function is called 4 times in the `CalculateBaseDamage`function. Let's remove these too.
```diff
- if (ShouldGetStatBadgeBoost(FLAG_BADGE01_GET, battlerIdAtk))
- attack = (110 * attack) / 100;
- if (ShouldGetStatBadgeBoost(FLAG_BADGE05_GET, battlerIdDef))
- defense = (110 * defense) / 100;
- if (ShouldGetStatBadgeBoost(FLAG_BADGE07_GET, battlerIdAtk))
- spAttack = (110 * spAttack) / 100;
- if (ShouldGetStatBadgeBoost(FLAG_BADGE07_GET, battlerIdDef))
- spDefense = (110 * spDefense) / 100;
```
That takes care of most of the boosts, but there is still the badge boost for speed, which we will handle next.
## 2. Remove badge boost from speed calculation
In the `GetWhoStrikesFirst` function of [src/battle_main.c](../blob/src/battle_main.c), there are 2 blocks of code with the comment `// badge boost`. These modify the speed during the calculation to take into account the badge boosts. Delete them:
```diff
- // badge boost
- if (!(gBattleTypeFlags & (BATTLE_TYPE_LINK | BATTLE_TYPE_x2000000 | BATTLE_TYPE_FRONTIER))
- && FlagGet(FLAG_BADGE03_GET)
- && GetBattlerSide(battler1) == B_SIDE_PLAYER)
- {
- speedBattler1 = (speedBattler1 * 110) / 100;
- }
```
```diff
- // badge boost
- if (!(gBattleTypeFlags & (BATTLE_TYPE_LINK | BATTLE_TYPE_x2000000 | BATTLE_TYPE_FRONTIER))
- && FlagGet(FLAG_BADGE03_GET)
- && GetBattlerSide(battler2) == B_SIDE_PLAYER)
- {
- speedBattler2 = (speedBattler2 * 110) / 100;
- }
```
This is the same check, but done for both battlers. And now that they are gone, all the badge boosts have been removed!
## 3. Update obedience levels
In [src/battle_util.c](../blob/master/src/battle_util.c), there is this block of code in the function `IsMonDisobedient`:
```c
if (FlagGet(FLAG_BADGE02_GET))
obedienceLevel = 30;
if (FlagGet(FLAG_BADGE04_GET))
obedienceLevel = 50;
if (FlagGet(FLAG_BADGE06_GET))
obedienceLevel = 70;
```
This can be replaced with whatever you like (it can even be removed if you want to remove this mechanic entirely!).
This is how it works for Omega Ruby/Alpha Sapphire, Gen 7, and the Let's Go games (for XY style, increase all the levels by 10):
```c
if (FlagGet(FLAG_BADGE01_GET))
obedienceLevel = 20;
if (FlagGet(FLAG_BADGE02_GET))
obedienceLevel = 30;
if (FlagGet(FLAG_BADGE03_GET))
obedienceLevel = 40;
if (FlagGet(FLAG_BADGE04_GET))
obedienceLevel = 50;
if (FlagGet(FLAG_BADGE05_GET))
obedienceLevel = 60;
if (FlagGet(FLAG_BADGE06_GET))
obedienceLevel = 70;
if (FlagGet(FLAG_BADGE07_GET))
obedienceLevel = 80;
```
Now, badge boosts are gone, and obedience has been updated to modern levels!
