Collecting Rank Points
Some Missions will only appear after you have filled your Rank Points bar to a certain level. This can be done either by participating in repeatable missions, or by trading crystals to any Conquest Overseer that can give you Signet. If you donate crystals beyond the point of filling your rank bar, the extra points will be added to your Conquest Points, and the Conquest Overseer will not accept any more.
