I took an interest in this and looked up the pilum on britannica online. The pilum was apparently 7 feet long, with a bullet-shaped or pyramidal head to let it penetrate armour and shields better. It was sometimes thrown.

Wikipedia, while less reliable, has more to say. It says the head of a pilum was almost a foot long, and capable of lodging in shields and armour it penetrated. The pilum could be rigged to bend at the joint between head and shaft - one of the two pins joining the parts could be replaced with a wooden dowel, which would snap under the shock of impact. Mechanical strain would then bend or twist the pilum, making it useless and encumbering shields it lodged in.

A suggestion to work this in Dominions would be (this would require dev coding, so we're in the realms of fantasy here):

Missile weapon with 1 shot.
Stats like javelin - perhaps a point or 2 more damage, perhaps less range and/or accuracy.
Special effect: If the missile is blocked by a shield, apply a new 'shield destroyed' effect (like armour destroyed but only affecting shields - armour destroyed would overwrite this effect).

I suspect this would increase the power of legionaries noticeably.

Btw, Nikelaos: Soft =/= light. See lead for details.
