The multiplier of their skill is meaningless in this, actually. The only thing that matters is that they use their skill.

For the x2 stuff, yes. For the 1/2, the Glossary seems to hint pretty hard that having half of something does *not* count as having it.

In particular, there's a bit of a cheat around the "two 1/2 Leadership counts as having a leader" rule, since "leader" is defined as "a personnel with OFFICER or Leadership". So, neither Toral nor Ja'rod is a leader, even though the game will shrug and let you count your AT/crew as having "one leader" with the two together - but yet, I'd argue that neither one *is* "the leader" if a card cared about that. (Note that they specifically *don't* count as Leadership for stuff).

So, if you're each contributing half a Diplomacy, should not the same logic apply? Yes, there's "a Diplomacy" skill in the AT/crew, but neither personnel contributed "Diplomacy".

But none of that is germane. As I summarized before:

Do they "use their skill to meet a mission requirement"? Via AoD, they "use 2 Treachery as if it were 1 Diplomacy".

So, each mission specialist uses their 1 skill to meet a requirement of the mission.

Lucky for y'all, this question was brought to my attention on Agenda Day, the day every month when I write up the Rules Committee's agenda for the month.

(Which, tbh, is mostly backlog from last month, partly because we did three rules releases in four weeks, partly because I got super distracted by elections.)

As a note, use (skills) seems to me to be explicit that this works:

Some cards allow your personnel to "use" a skill like this in place of another skill that they already have. The levels of the original skill may come from any combination of personnel, who are treated as having a fraction of that skill proportional to their contribution. For example, The Art of Diplomacy allows your personnel to use 2 Treachery as if it were 1 Diplomacy. With this card, two personnel who have Treachery can provide 1 Diplomacy (each replaces their Treachery with Diplomacy x1/2), while another personnel who has Treachery x2 can provide another Diplomacy (Treachery x2 is replaced with Diplomacy x1). See skills - skill multipliers. On a mission specialist, this counts as "using" a specialist skill for Assign Mission Specialists. A personnel may not use their skill as the new skill and the replaced skill simultaneously.

On a side note: almost nothing you can do with AMS is as stupid (to my mind) as the routine use of Preserver Obelisk with attribute requirements.
