Should be one of these I guess:
Code:
* PrepareChampionPurchaseRequest(*bool* _respecNeeded_)
* AddSkillToChampionPurchaseRequest(*integer* _championSkillId_, *integer* _newPendingPoints_)
* AddHotbarSlotToChampionPurchaseRequest(*luaindex* _slotIndex_, *integer* _championSkillId_)
* GetChampionPurchaseAvailability()
** _Returns:_ *[ChampionPurchaseResult|#ChampionPurchaseResult]* _result_
* GetExpectedResultForChampionPurchaseRequest()
** _Returns:_ *[ChampionPurchaseResult|#ChampionPurchaseResult]* _result_
* SendChampionPurchaseRequest()
* GetChampionDisciplineId(*luaindex* _disciplineIndex_)
** _Returns:_ *integer* _disciplineId_
