Although the act of summoning a Daedra Prince is no common service, it is one nonetheless. The only reason to summon a Daedra Prince is to gain possession of a certain artifact. Not many can perform this service, therefore the access is restricted. People of noble origin have their means to access a Daedra Summoner, it is rumored that every ruler has his own Daedra Summoner at court. Common people can access a Daedra Summoner only within the services of certain Factions. However this special service is restricted to high-ranking members within these factions and the cost are in most cases exorbitant. There are rumors, that certain Witch Covens can also summon a Daedra Prince for whomever has the required amount of gold.
Daedra Princes request a certain service from mortals that dare to appeal to them. If the mortal completes the duty to the satisfaction of the Daedra Prince, he or she might grant him the possession of a legendary artifact.
 Detailed Information
There are three ways to summon a Daedra Prince:
- Using the service of Daedra Summoners of the Mages Guild, available to members at rank 6
- Using the service of Daedra Summoners of one of the eight Temples, available to members mostly at rank 7, except the School of Julianos (rank 6) and the Resolution of Zenithar (rank 8)
- Using the beldam of a Witch Coven, including its followers found sometimes in cities and witches that can be found in dungeons like the witch of the Knight Order quest The Artifact
Daedra summonings at the Mages Guild or temples can be done only on certain days (see Summoning Days).
At witch covens the situation is completely different. It seems that hazard alone determines which Daedra Prince can be summoned on which day. You can of course just visit the coven everyday until it summons the Daedra Prince you want.
Although Sheogorath has his own Summoning Day, there is a 5% chance at every other Summoning Day that he shows up instead of the Daedra Prince whose Summoning Day would be normally. A common circulating rumor, also mentioned in the book Wabbajack, says, he can be summoned during a thunderstorm as well. This rumor could not be confirmed.
There are five different sorts of weather in the game These are
- Snowing (in High Rock during the winter months)
Hence Raining would be the closest weather to a thunderstorm. And as a matter of fact, Sheogorath can not be summoned on such days when there is no Summoning Day. Also the probability, that he turns up unexpectedly doesn't seem to be higher than the usual 5% when it is raining on Summoning Days.
 Summoning Costs
The costs for summoning a Daedra Prince are quite high and are determined by reputation factors alone. The exact costs are calculated as follows:
200,000 gold − (Reputation with the summoner's faction × 1000 gold)
That means a reputation of 100 with the corresponding faction lowers the costs per session to 50% of the base price.
Regarding this formula the best choice, if you have one, would be the Daedra Summoner of the Mages Guild because
- Your reputation with him is the same as with The Mage Guild as a whole. Therefore you need at least 20 successful quests for the Mages Guild for a total reputation of 100.
- Summoners of temples are only subgroups of their temples, therefore you only get 2 reputation points with them for every successfully completed quest. So you will need at least 50 successful quests to acquire a total reputation of 100 with them.
- If you successfully complete at least twenty quests for a witch coven, you will also have a total reputation of 100 with the beldam at the end, but finding a witch coven without any hints is a pretty difficult if not an impossible matter. There is only one quest in the original game which points to a coven, Business with Vampires which reveals the Kykos Coven in Dak'fron. In addition, lycanthropes may get a hint pointing to the Glenmoril Coven in the Ilessan Hills, but these witches only summon Hircine. Two other quests The Daedric Book and The Thieves Gang, that should reveal the Skeffington Coven in Phrygias respectively the Coven of the Tide in Myrkwasa to the player, are broken in the original game. The covens will not be revealed unless a patch for these quests is installed. There are no rumors or books about any covens' locations. If one is very, very lucky, then one may receive a dungeon map which reveals the location of a coven, but only in a region which actually has a coven, and even then the chances to get such a dungeon map are marginal since, according to the law of probability, the calculation
1 ÷ (Number of unrevealed dungeons in the region)is terribly low.
 Chances for a successful summoning
The following information comes from The Daggerfall Chronicles and must be taken as fact, since there is no way to verify this information by game-play alone.
The DF Chronicles gives the following formula:
Chance(%) = 30 + player's reputation with specific Daedra + special day + weather type
- The special day is the day on which the specific Daedra can be summoned; according to the DF Chronicle this adds an additional chance of 30% at this day and 0% at any other day. But since the Daedra can't be summoned on any day beside the summoning day, it is arguable whether this variable may have any influence at all.
- The weather type is the type of weather the specific Daedra enjoys the most, it increases the chance by 15%.
According tho the DF Chronicle these are:
The remaining Daedra do not have a favorite weather type, therefore the additional 15% are always applied.
As it was already mentioned further upwards, there is no way to determine if the weather type Thunderstorm does exist and if it does, there is no way to tell if it is the type of weather at the moment.
According to the DF Chronicles, the maximum chance for a successful summoning is 95%. The remaining 5% are for Sheogorath appearing, which will raise to 15% during thunderstorms, according to the DF Chronicles.
If the summoning was successful , but the player declined the Daedra's quest, waves of one of the five daedric foes will appear to punish the player for three in-game hours, after this period they will return to Oblivion.
When a summoning at a witch coven was not successful, the daedric foes will also appear, at guilds they will not.
Considering all these circumstances, it is therefore a wise choice to always save the game before performing a Daedra Summoning.
- Note: Game-play experiences however indicate, that the daedric punishment feature has only a very marginal chance of actually occurring.
