Because clearly we need more chaos…
Not only is Metus’ dagger-thing apparently an axe, but…
These are all staves.
Bident? Staff. Giant axe? Staff. Weird hammer-thing? Staff. Mace? Staff. Weird scythe-thing? Staff. Pike? Staff.
Other staves in Bionicle: Takanuva and Teridax’s scythes, all of the Turaga’s tools, which include buzzsaws, hammers, tridents, and pickaxes, all of the Rahkshi’s double-ended glaives, all of the Rahaga’s tools, Takua’s blade on a stick, and pretty much every other weapon that involves one or two weapon parts and a stick.
So while Chiara is stuck with a spear (so definitely a pointy bit on a stick), and Orde is stuck with a mace (notably not a “spiked” mace this time, so probably not Actually A Morningstar like Helryx’s, yes they’re different weapons), Zaria… well…
Basically there’s precedent in Bionicle for just about every weapon under the sun to count as a staff as long as there’s a long axle attached to the back end of it. Hopefully, this means you can modify your Zaria MOCs to fit within this new headache with as few as one piece.
Yes, I want to see guns on sticks. If we can have a Rhotuka Launcher on a stick count as a staff, then I don’t see why other launcher-type weapons attached to sticks can’t count as a staff.
The hammer on Kodiak’s current version probably doesn’t even need to change that much, Onewa’s badge of office and Matau’s Combat Staff are both staves and also hammers, after all.
Basically, “Staff” gives an enormous amount of wiggle room and we should make the most of it.
EDIT: Vahki staves.
Two pincers and four swords now count as staves.
