The manual also talks about updated naming for Actor Weapon Sprites, but I'm not using Actor Weapon Sprites, I'm just using the action sprites, so they all have defaults for swords or spears, and everyone apart from one archer uses a sword style weapon to begin with.
The error in question is this:
The lines in the manual I have been following are these:
Quotenormal spriteset - lord marius.png
attack spriteset for swords - lord marius_atk1.png
attack spriteset for flails - lord marius_atk3.png
Additionally you have to specify weapon sprites for the types. The sprites have the same name as the attack sprites with _wpn added behind. This is necessary because weapon sprites can be displayed under the enemy and need to be separated from the actual action sprite.
example:
normal spriteset - lord marius.png
weapon spriteset for spears - lord marius_wpn2.png
weapon spriteset for shuriken - lord marius_wpn7.png
The names of my sprites being:
Barlak.png, Barlak_atk1.png, Barlak_def.png, Barlak_itm.png, Barlak_skl.png, Barlak_wpn1.png
The dimensions of the atk and wpn sprites are the same, these all worked with the previous version of Blizz ABS, and not to be an ass, but if someone is going to refer me to the manual again can they at least tell me the page rather than just "It's in the manual". The manual is 31 pages, and the Sprite Control section I've been reading hasn't been telling me anything new.
