// by 1 or 2 by spending 1 or 3 IP
// 6) In addition, substract the left number value (data.vassals.influence) if game.who is Lancaster, add if game.who is yorkist
// 7) Roll a die : <= current influence rating success, => failure. 1 always success, 6 always failure.
// 8) Place one vassal marker on the lord mat
// 9) Place the other vassal marker on the calendar box a number of turn equal to current turn + service (data.vassals.service)
// 10) When the turn reaches back the face down vassal, the vassal marker on the calendar dissapear and the one on the map is turned face up, ready to be mustered again
