Warrior effect (Raging Javelin) causes CTD if triggered with empty hand

[darkcolouredbox]

To reproduce;

Acquire [Goliath] for the (Earthshaker) effect, and [Bound] for the (Raging Javelin) effect.

Trigger (Earthshaker) by jumping from a height, near a hostile mob, while holding an item.

• This will trigger the effect as intended, no crash.

Trigger (Earthshaker) by jumping from a height, near a hostile mob, with an empty hand.

• The game will immediately crash to desktop, erroring with

  Cannot invoke " ... " because "model" is null
