Someone in another thread made mention of letting the Summoner make a staff with Summon monster IX and it only being a '6th' level spell so it could be recharged at a 'discount' when handed off to wizard (6th level slot instead of a 9th).
This brought up an interesting question regarding the Summoners spell list and SLA.
Would the staff be recharged at a discount because of the "lower" spell level of the Summoner.
Also, what level is the Summoners Summon monster IX SLA? 6th? 9th? A summoner could take 'Empower Spell-Like ability' if SMIX counts as 6th level, but not if it counts as 9th
Does magic item creation/Feats assume spells to be based on the standard wiz/sorc progression?
