7.4.4.a Seasoned is a passive ability that appears on Characters.
7.4.4.b If an object with Seasoned would move from the Expedition zone to the Reserve, it keeps its boosts as it moves.
Remark. In order to keep its boosts, the former object in the Expedition zone needs to have Seasoned; the new object in Reserve does not need to have it.
7.4.4.c Seasoned applies to any move from the Expedition zone to the Reserve, including but not limited to the Rest daily effect at Dusk.
