What?
Misty step uses one of his 2 x 2nd level slots (taking away a smite). He only has 2 x 2nds for those 6 encounters (and 4 x 1sts).
Im struggling to see how he outshines the Artificer over 6 encounters, barring you not keeping a close eye on his resource expenditure as DM.
What was casting Chain Lighting vs 6th level PCs?
It deals (on average) 45 damage to every single PC (barring a successful Dex save, which is unlikely for many PCs of that level vs the likely save DC of 15 or so) likely resulting in a TPK.
CR 8 or 9 invoker.
They also had another encounter with a spellcaster.
Alot of them have absorb elements.
