Starfinder Differences

[liamfisher]

I interpret the "The ally does not participate in combat" clause as it gets no initiative and none of its own actions in combat.  But if you use your own actions you can still benefit from the skill bonuses it provides.  But yes, if you are unconscious it doesn't function as you have no standard action to use as you would any other skill.

Right but for the cost of the fame for this, you're better off just using a serum, it's more cost efficient
and heals you more.

In either case you still have to be stable and have a standard action to use.

They can't do anything in regular or ship combat, but they CAN help repair things or fix
stuff in between. Participating in combat means doing anything during a combat round.

They are literally just a roll when you wouldn't normally be able to make one, but only
outside of a combat round.   I was told I couldn't use one for an engineer while I was 
piloting. Same as why a drone can't be your engineer as well.
