Frondeuse clarification

[Rogue]

How does the Frondeuse use her worm slinger?

this is all in the rulebook but scatter under different abilities so here goes:

The slinger is affected by the Artillery rule therefore the Frondeuse needs to be in contact with her servant to shoot. Furthermore the Worms are ammunition of the heavy type so she cannot move before shooting (for example start in contact with servant aka recharge, make a few steps, before throwing the worm).
