Online:Quest Timing

Quests to Do as Soon as Possible
These are quests with long term benefits which you will want to take advantage as soon as you can.

:Joining the Mages Guild and Fighters Guild as early as possible has the immediate advantage of making the Persuasive Will and Intimidating Presence skills available, which can reduce the leg-work in many future quests.  Joining the Fighters Guild in particular is something you'll want to do as soon as possible, since advancement in the guild is earned by killing undead and daedra, but only if you are already a member. Advancement in the Mages Guild comes from reading Lore Books, but unlike the Fighters Guild, books you read before you join will be counted towards your rank.

;The Main Quest
:Besides earning a number of skill points, completing these quests is the only way to increase your rank in the Soul Magic skill line.  In particular, getting the Soul Lock skill will provide you with a steady supply of Soul Gems without wasting a skill slot on Soul Trap.  Completing these quests up to The Weight of Three Crowns will give you access to Coldharbour for the first time (though you can get there early by porting to another player).

;Crossing the Chasm
:Completing this quest will grant you access to the Fist of Stone, the northernmost section of the Coldharbour zone which otherwise cannot be reached on foot. This is mainly relevant for the purposes of collecting the skyshards located there. Note that you can get there early by porting to another player, thereby skipping this requirement.

;All quests in the Mages Guild and Fighters Guild
:These are a good source of skill points for early players.  You won't be able to do them all immediately, since they have guild rank requirements, but doing each of the quests as soon as you are allowed is a good idea.  The Mages Guild in particular has a potential reward of two skill points for the last quest, and completing them also unlocks the Eidetic Memory collection of books, allowing you to keep track of all books and notes you've found.

;Welcome to Cyrodiil, Siege Warfare, and Reporting for Duty
:These three quests introduce you to the PvP mechanics in Cyrodiil.  Even if you have no interest in PvP play, it's a good idea to do these quests as early as you are able upon reaching Level 10.  These quests involve no actual PvP encounters, and will grant you access to the Assault and Support skill lines (though you will need to do some PvP content in order to advance these beyond the first skill in each line.)  The first two Assault skills are useful outside Cyrodiil. Vigor, provides stamina-based healing. The Continuous Attack passive is very useful for getting around outside of Cyrodiil.  This skill becomes available at line rank 3 on the Assault skill line, so some PVP play is required to unlock it. Siege Shield is not that useful outside of Cyrodiil, though the Propelling Shield morph does increase projectile range elsewhere. Completing enough PvP content to raise your rank to Sergeant (line rank 7) will grant you access to all of the other Alliance War skills, many of which can be very useful outside of PvP areas.

;All of the Crafting Certification quests
:These will allow you to take Crafting Writs, which are not only easy money and experience, but also very helpful in acquiring crafting materials and raising your crafting skills.  If you have access to Summerset, add Jewelry Crafting Certification to the list.  Even if you are not interested in becoming a master crafter, being able to do writs early on can be useful later on, particularly during the annual Jubilee Events, where you can earn rare crafting motif pages for every writ turned in.  Even if you have no interest at all in crafting motifs, they are worth a great deal of money on the markets, so this can be a great source of fast income.

;Bosmer Insight
:Completing this quest allows you to use shrines throughout Grahtwood which grant you one of three buffs for an hour.  While these can only be found in Grahtwood, their bonuses continue to benefit you even after you leave for the duration.   At the very least, it is beneficial to make this one of the first quests you do while in Grahtwood.

;Voices in the Dark 
:Completing this quest grants you the Dark Brotherhood skill line and access to the Blade of Woe.  If you have any intention of becoming a career criminal, being able to assassinate potential witnesses quickly and potentially without witnesses will save you a lot of money on paying off bounties.

;The Queen's Decree and The Psijics' Calling 
:If you have access to the Summerset chapter, you'll want to do these two quests as soon as possible, because they will grant you the See the Unseen skill for free, which allows you to see and loot Psijic Portals, which can provide a variety of unique rewards.

Quests to Save for Later
These are quests which may make certain things harder if done early.

;House and Home and One Fell Swoop
:If you are trying to complete Kari's Hit List for the Thieves Guild, the artifact found in Velyn Harbor is much easier to steal before liberating the city.

;Sparking the Flame
:After completing this quest, the town of Bleakrock Village will be overrun by hostile invaders.  If you had any business you wanted to do on the island, it is much easier to get it done before this. Once you've done all the quests on the island, however, there's pretty much no reason to ever go back.

;Legitimate Interests
:Completing this quest will cause the Red Rook occupiers in Crosswych to become openly hostile to you rather than just neutral.  After completing The Miners' Lament and Crosswych Reclaimed, they will be replaced by Covenant Guards.  If you are criminally inclined, the town is ripe for the picking prior to these three quests since there are no guards and the Red Rooks don't really care if you break the law.
