Yep, just the Henry VI Block, as he does not get the King Office Block. Embassy events are tough on Henry :-)...but at least the Lancaster player knows there will not be combat in that Shire in the current round.
Yet another use for "Love Day" if Henry is sitting all alone in a Shire surrounded by "bad guys" :-).
No, 10.3.3 is clear that it is /only/ combat effects that remove him from the game. Being reduced below retainer strength via attrition, plague, etc. treats him like any other Heir. See 10.3.3: "If the Henry VI Block is eliminated in combat (i.e., reduced below Retainer Strength) or his Host Noble suffers a combat result of Killed on the Elimination Chart (20.6.1) ..." (emphasis added).
...this troublesome king.
What will happen if Embassy is played and Hank is king? Will he go all by his lonesome, or will his host accompany him? Rules seem to imply the former, but not sure.
If Hank is reduced below retainer strength for reasons other than combat, eg plague, desertions, will he suffer the same effects as if eliminated in combat?
