This tutorial did not include the held item effect changes, so I've added those.

+## 4. Edit the held item effect
+
+So far, we've only edited the outside of battle effects of the Sitrus Berry. Go to `src\data\items.h` and look for the Sitrus Berry. There are two important lines here:
+```diff
+        .holdEffect = HOLD_EFFECT_RESTORE_HP,
+        .holdEffectParam = 30,
+```
+We'll want to change these to:
+```diff
+        .holdEffect = HOLD_EFFECT_RESTORE_PCT_HP,
+        .holdEffectParam = 25, //restores 25% of the max HP
+```
+
+If you're using the battle engine by Dizzyegg/rhh, you're all done! Otherwise, you'll need to do step 5.
+
+## 5. Add hold effect define and usage
+
+Go to `include\constants\hold_effects.h` and define a new hold effect:
+```diff
+        #define HOLD_EFFECT_RESTORE_PCT_HP 67
+```
+
+Now go to `src/battle_util.c` and look for this section in the function `ItemBattleEffects`
+```diff
+            case HOLD_EFFECT_RESTORE_HP:
+                if (gBattleMons[battlerId].hp <= gBattleMons[battlerId].maxHP / 2 && !moveTurn)
+                {
+                    gBattleMoveDamage = battlerHoldEffectParam;
+                    if (gBattleMons[battlerId].hp + battlerHoldEffectParam > gBattleMons[battlerId].maxHP)
+                        gBattleMoveDamage = gBattleMons[battlerId].maxHP - gBattleMons[battlerId].hp;
+                    gBattleMoveDamage *= -1;
+                    BattleScriptExecute(BattleScript_ItemHealHP_RemoveItem);
+                    effect = 4;
+                }
+                break;
+```
+You're going to want to add another case directly below this case. Copy paste this in:
+```diff
+            case HOLD_EFFECT_RESTORE_PCT_HP:
+                if (gBattleMons[battlerId].hp <= gBattleMons[battlerId].maxHP / 2 && !moveTurn)
+                {
+                    gBattleMoveDamage = (gBattleMons[battlerId].maxHP * battlerHoldEffectParam) / 100;
+                    if (gBattleMons[battlerId].hp + battlerHoldEffectParam > gBattleMons[battlerId].maxHP)
+                        gBattleMoveDamage = gBattleMons[battlerId].maxHP - gBattleMons[battlerId].hp;
+                    gBattleMoveDamage *= -1;
+                    BattleScriptExecute(BattleScript_ItemHealHP_RemoveItem);
+                    effect = 4;
+                }
+                break;
+```
+
 That's all!
