The level 20 ability of the Arcane Bloodline, Arcane Apothesis allows you to spend 3 spell levels in order to fuel one charge, for instance in a staff.
Now Staff of the Master allows you to use Metamagic feats you possess by spending charges equal to the level of the feat you are trying to use.
So would this allow a high level Sorcerer with the Arcane Bloodline to fuel their metamagic feats by burning low level spell slots? So for instance the sorcerer would be able to Quicken a level 9 spell by burning 12 spell levels in any combination (such as using 3 level 4 spells)?
