Does anyone recall the height equation, or whatever it is, to determine if a spear or staff can act as a walking stick by a given character?

Most spears, sticks, polearms and staves have worked for Delia so far. I think if it is around half your height, you can use it(?).

Luminier is exactly 180 cm. The rider lances are 300cm and it's too long for him. A lance that is 240cm is classed as a walking stick for him, but still makes him rather tired if he tries to move quick. So you can go by that.
