Ah, my bad, was used to the 3.5 version.  Yes, you can cleave from a tentacle to the main monster just fine (you could also cleave from one monster to another, but not from a monster to a tentacle).<br/><br/>And yes, your smite bonus works against the tentacle, since they're part of the same monster.<br/><br/>Anyway, what are your guys' thoughts on the system so far?  Anything that stands out as odd or clunky?
