To clarify the above, the Dark Fantasy pack also comes with normal-sized (chibi) battlers as well, such as 2_DF_Actor1, etc. You only need the weapon adjustment stuff if you use the taller sv battlers, which are all prefixed with a 3, so 3_Actor1_1 and such.
Personally, I think it's a shame RMMV settled on the chibi style, because the taller style looks really good. Oh well!
