I´ve noticed this issue discussed, and am not sure what the intent is myself.
When using Word Burning, is the final ´cost value´ (?) of a Spell Slot limited to LESS than the cost value for the next highest Spell Level? Or is there no limit whatsoever?
At first I thought there wouldn´t be much advantage in super-Augmenting a low level spell (besides Concentration checks), since it still has the lower DC and spell level (vs. effects like Globe of Invulnerability).
But then I thought, what about Quicken? Being able to fit a huge amount of effects into one low level spell compatable with a Lesser Rod of Quicken, for example, lets one get off a ton of effects for just a Swift Action... Which may be more than the intent here. Sure, one single spell is Dispellable in one go, but many effects can be Instantaneous (besides not having a Save dependent on Spell Level) and relying on Dispel as a balancer doesn´t seem prudent to me.

Should the minimum Spell Level of Effect Words have a Boost Value like costs do? Should there be a mechanism to increase minimum Spell Level per additional Effect(s)?
