The alchemical homunculus of the AU 2019 artisanal agent is described with a list of actions that he can perform, most of them. causing the craftsman to use a bonus action to clear the order. The listed actions are Dodge (default option when no command is issued), Dash, Disengage, Help, Acid Spitle and Alchemical Salve. In particular, the description gives the impression that it is the only actions that the homunculus can be instructed to perform:
In combat, the homonculus shares your count of initiatives, but it takes its turn immediately after yours. The only action that he in turn performs is the action of dodging, unless you take an additional action in turn to order him to take one of the actions of his block of statistics or perform the action Dash, Disengage or Help.
The description never explicitly says that the homonculus can not perform other actions, but if we take the wording literally, it seems that ordering him to perform another action is not possible at least not in combat – it will simply take Action Dodge.
To add another complication, the homunculus may not be physically able to perform certain actions. The examples given for the appearance of the homunculus do not include hands, for example (not underlined in the original):
You determine the appearance of the homunculus, which includes wings and pieces of alchemical equipment. Some alchemists prefer mechanically looking birds, while others like winged flasks or miniature cauldrons.
In addition, the Languages section of his statistics block says "understands the languages you speak," which implies that he can not speak.
Thus, considering both its physical capabilities and the mechanism of issuing orders, what other actions, if any, the alchemical homunculus can be forced to achieve? The "normal" actions listed in the ground rules that do not appear in the description of the alchemical homunculus are: Attack (presumably a bare-handed strike), Hide, Ready, Search, Use a object and of course improvise an action. In addition, some magic items require an action to be activated (separate from the normal action using an object) or a command word. If the homunculus can perform any or all of these actions (and that it can be ordered to execute them), does it matter whether or not it is in combat? Are there any actions that the homunculus can undertake without the need for an order, such as feeding a healing potion with its master when it is knocked out (and therefore unable to give the 39; order)?
In addition, although the homunculus alone can not perform bonus actions, it could perhaps be assigned a magic object activated by a bonus action. In this case, could the homonculus activate the item (and can it be ordered again)?
Note: Another similar question has already addressed the question of mental the capabilities of the homonculus, but the answers do not address its physical capabilities nor the possible limitations of the mechanisms of order setting.
