Right...
Thingy of Assorted Polearms: (also known as the Polearm Emporium Thingy) This unshapely thing (made of metal and wood Things - about the size of a Wand) can change shape and turn into a random polearm on the push of a button.
When the button is pushed, roll a D20. The Thingy turns into one of the following polearms:
1 - Glaive or Glaive-guisarme (roll 1D2 for type)
2 - Voulge
3 - Guisarme-voulge
4 - Spetum
5 - Bill or Bill-guisarme (roll 1D2 for type)
6 - Partisan
7 - Ranseur
8 - Military fork
9 - Morning Star
10 - Fauchard, Hook fauchard or Fauchard-fork (roll 1D3 for type)
11 - Lucern hammer
12 - Halberd
13 - Bec de corbin
14 - Bardiche
15 - Awl pike
16 - Trident
17 - Mancatcher
18 - Spear or Long spear (roll 1D2 for type)
19 - Lance (roll 1D4 for a Light/Jousting/Medium/Heavy Lance)
20 - Greatclub
The Thingy changes shape and functions as the polearm type for 2D6 rounds. It then reverts to it's Thingy shape Again, and is inert for 2D6 rounds. The button can then be pushed again.
So there.
