Upgrades are enhancements made to your held/worn objects. You can be assumed to have applied any upgrades you have selected to any appropriate item you are using after at least a short rest since acquiring the item.
Each slot can only hold one upgrade (per Artificer rank) at a time. You are allowed to know more upgrades than you have slots for, but you can only apply as many as you have slots for.
Increase your size category by one, along with +4 bonus to Str, -2 to Dex, -2 to Con, +2 to reach, +1 to melee damage rolls, and +x to carrying capacity.
Gain a Jump movement type equal to walking speed. Also nullifies falling damage.
Servitors
You can have one servitor active at a time. If you have more than one, they begin to act on their own, and may even turn hostile.
It is a swift action to give your servitor a simple command (move here, attack that, deliver this item to that person, etc). They act on your turn in combat. By default, they use hearing to understand your commands; assume they understand your language.
Create a wood golem servitor: a large humanoid automaton made of wood that can fight alongside you, heal itself by absorbing sunlight, and lend you its vitality when you need healing.
create zones of lesser or greater gravity, or even anti-gravity

Dev Notes
