Quest Sync

Quest Sync or Level Sync is a mechanic introduced in Heavensward for Quests that employs an automatic level adjust system.

Quests using this system will have their difficulty and EXP rewards adjusted to match your current level within the expansion's level range. Heavensward quests will sync from level 50-60, for example, and doing quests at a higher level than the maximum sync will sometimes result in reduced EXP rewards.

Not every side quest uses Quest Sync, but all Tribal Quests do beginning in Heavensward, and so do all Side Quests beginning in Shadowbringers areas. If a quest uses sync it will display this message in its quest box:
※Please note that the difficulty of this quest has been synced to your current level.
