Conjure Rust Monsters

You summon rust monsters that appear in an unoccupied space that you can see within range. When you cast this spell, you may choose to summon up to four rust monsters. A rust monster summoned by this spell disappears when it drops to 0 hit points or when the spell ends. The summoned creatures are friendly to you and your companions. Roll initiative for the summoned creatures as a group, which takes its own turns. These summoned creatures will obey any verbal commands you give them (no action required by you). If you give them no commands, they will seek out the nearest sources of metal to eat, only attacking to defend themselves, or if there is no unattended metal nearby.
