Leadership.

[demonsbane]

Would I be right that if the player wishes to use leadership to give a boon, to another player then they must expend Significant Action not a minor.

[AnotherDilbert]

Not defined, it is not listed under any action type.

I run it as Significant Action.

[ShawnDriscoll]

Lending any kind of help tends be a major action of some kind by another Traveller. Just like in movies.

[Condottiere]

Depending on whether it's active or passive.

Rallying the troops is an active activity.

Basking in the afterglow of a leader's presence would be passive on his part.

[Varulv]

I run it as a significant action with an average (8+) task or hasted as a minor action with a difficult (10+) task roll.
