The issues I had were as such,

Simon really shouldn't be able to cast speak with dead more than a couple times, much less any of his other spells (the Cleric's token might be a magic item rather than just a focus?)

The druid (I forget her name) really shouldn't be able to wildshape more than 2 per day (Unless she's 20th level which is unlikely), additionally she shouldn't be able to turn into an owlbear (this one is handwavy)

Dragons in DND don't breathe flammable gas, they breathe magical flame, which is made with built in magic.

Also Dragons can talk, no idea why this one didn't.

I caught both of the first two, the third one makes sense for the change and personally I would have done the same as a DM just for the tiny exploit given to the players. The final one is like how the bard didn't cast spells.

Yeah, no idea why he didn't use spells. The paladin was such a DMPC, basically just a plot device (again why no spells)
