+### AI might use its base reward value as an item
+
+In the `AI_TryItem` routine, an item pointer is set to `wEnemyTrainerItem1` and then increments to `wEnemyTrainerItem2` to see if either of the AI's items are in the `AI_Items` list. However, if the AI has used its first item (or its first one is `ITEM_NONE`) and hasn't used its second item, the item pointer can increment from `wEnemyTrainerItem2` to `wEnemyTrainerBaseReward`. If the value at this address then matches an item in the `AI_Items` list, the AI could mistakenly use it.
+
+**Fix:** Edit `AI_TryItem` in [engine/battle/ai/items.asm](https://github.com/pret/pokecrystal/blob/master/engine/battle/ai/items.asm):
