Man Battle Stations!
In the field, a Colossus is not dependent upon the support of others, but this is not to say he cannot benefit from their presence. A skilled crew can be invaluable to an Alchemical who’s Transfiguration provides him with the capacity to use them.
Characters working as members of an Alchemical’s crew always provide a limited teamwork bonus (Exalted, Page 125) to his actions if it is remotely plausible that they could do so. This can apply even in combat, where an Exalt’s gun crews might provide this bonus on attacks (commonly offsetting multiple-action penalties for firing multiple weapons), or a bridge crew might assist in processing sensor and communications data.
When deemed appropriate, a Colossus can also release control of some of its systems – typically things like weapon mounts, but potentially others at the storyteller’s discretion – to the control of heroic crewmembers. In such a case, the system in question is operated by the specified character, but the Alchemical may choose to supplement that character’s actions with his own charms, subject to normal rules for charm use.
