Edwin Odesseiron

"Greetings. I am Edwin Odesseiron. You simians may refer to me merely as "sir" if you prefer a less... syllable-intensive workout."

Edwin Odesseiron is a lawful evil human conjurer and a potential companion.

Edwin and Viconia are the two non-game canonal companions.

Recruitment
Edwin is available to recruit from Baldur's Gate Chapter 2. You can acquire him on a bridge at Nashkel near the Belching Dragon Tavern. He asks you to help him find and kill the witch Dynaheir, another potential companion. Normally it isn't possible to have both Edwin and Dynaheir in the same party because the player character has to choose a side between Edwin and Dynaheir & Minsc, if the party brought him as well. A workaround for this problem is that the party can acquire Edwin after saving Dynaheir from the Gnoll Stronghold. At this point there'll be an option to take him along and Edwin says he will keep an eye on her.

Quests

 * Edwin and Dynaheir (You must complete this quest within time limit)
 * Rescuing Dynaheir – will want to kill Dynaheir upon rescuing.

Relationships

 * Ajantis Ilvastarr will eventually attack any of the evil party members, but you can call him off by controlling him to do something else
 * Dynaheir - Conflict
 * Neera - They can't be in the same team

Gameplay
In BG1 his family amulet which can't be removed gives him an additional spell per spell level in addition to his conjurer specialization which gives him another spell per level with the penalty of not getting divination spells, the increased XP cap of TotSC lets he cast up to three level 5 spells. He has the second highest intelligence among other companions. His constitution score of 16 grants him an additional adjustment of + 2 hp per level which is the maximum for non-warrior classes. He is one of the best wizard companions in game, rivaled only by Baeloth.

A trick to use him is to equip him with two Rings of Wizardry so he's capable of casting 20 magic missiles per day at level 9. This however, is not possible in enhanced edition of the game because you can only wear one Ring of Wizardry.
 * Enhanced Edition note: Companions who are under-leveled at the time of joining will be given a certain amount of experience points (XP) for you to manually level them up to gain more control of their status.

In-game biography
"When asked about his past, EDWIN sneers that he has no intention of revealing such information and that it is none of your business. He further states that you are lucky enough to simply share his company, and then mutters something about leaving whenever he wishes. He obviously cares little for the camaraderie of others, and seems to take more pleasure in speaking to himself than in interacting with the party. His attire brazenly displays the colors of the Red Wizards of Thay, though why a member of that organization would come so far west is puzzling. Edwin does not seem forthcoming with any information."

Recruitment
Edwin is available from Chapter 8. You'll see him storming east of the army camp at Coast Way Crossing, angrily mumbling about Caelar, you can convince him to join the party once he sees that you share the same goal.

In-game biography
"When asked about his past, Edwin mutters darkly that you already know more than is good for you. Edwin mutters quite often to himself, apparently preferring his own conversation to that of others. Despite his eccentricities, Edwin is a powerful and intelligent mage, as evidenced by his membership in the Red Wizards of Thay. Edwin grudgingly admits that he and several other Red Wizards were on a journey when they were waylaid and pressed into service by Caelar's crusade. Two of his allies joined the crusade, and a third was slain. Edwin escaped, vowing vengeance on Caelar. He frequently refers to the Shining Lady as "witch," an obvious slur given that the Red Wizards' hated enemies include the Witches of Rashemen."

Recruitment
Edwin is available from Chapter 1. He can be recruited in Mae'var's Guildhall during Find proof of Mae'var's Treachery, a part of thief stronghold quest.

Related quests

 * Find Proof of Mae'Var's Treachery
 * Find the Nether Scroll for Edwin (There's a timer for this quest)

Relationships

 * Minsc - Conflicts
 * Valygar Corthala - Conflicts
 * Neera - They can't be in the same party

Gameplay
His family amulet now gives him two additional spells per level instead of one in BG1, the total bonus for him would be three extra spells per spell level as he's also a conjurer. His intelligence score of 18 makes him the only companion able to gain level 9 spell slots with no need of intelligence boost. His only drawback is not accessing to divination spells which is a minor issue for the game offers plenty of other ways of casting True Sight.

Considering the overall powerness of the mage spell pool, especially some "law-defining" spells like Improved Alacrity, Time Stop, Chain Contingency, Project Image, Improved Haste, Protection from Magical Weapons, his unique +3 spells/level pushes him to a much higher ground once high level spell slots are unlocked while others are inevitably restricted by the limited numbers of castings.

Edwin in BG2 is literally one of the, if not "the", most powerful companions in game. He's very overpowered.

In-game biography
"When asked about how he came to be in the employ of the Shadow Thieves, EDWIN sneers that it is none of your business. In his opinion, you are lucky enough to have encountered him at all, and further inquiries beyond this initial boon will only serve to tempt the fates. Despite his obstinate nature, there is a hint that his present circumstance is not all that favorable, and his willingness to join with you contradicts his supposed distaste for the company of others. Edwin ignores speculation about his recent past, but he does appear to have placed less emphasis on the Red Wizard colors he has so brazenly displayed in the past. It is an understandable act for a wizard traveler in mage-fearing Amn."
