I have a question. (Lore)

Do Lord Exultants use their spears as a spear or just as a sword? (In the lore) I was wondering because in a Warhammer game trailer I saw how they used their spears as a sword, and it looks more like a sword than a spear.



So I was wondering if it serves as a spear or is it like a sword with a longer handle?



I love the design of the Phoenix Power Spear, but I was curious.
