• ::companions - list your roster (names, combat levels, current order).
• ::companion <train|follow|deploy|return> [slot] - set orders: train (auto-fight to level up), follow (guard you), deploy (independent offense), return (recall).
• ::companion equip <slot> <itemId> / unequip - gear them from your bank (they have their own equipment).

Companions persist between sessions and respawn if they fall. They're a force multiplier for PvM and a head start in the war.
