“This is just like the image I saw at the Tower of Blaggi... A youth with the Light of Zwei...strong power... Bishop Claud... It is just as you said...”
—Sleuf, describing Leif
He can be recruited in Chapter 16A if the player had previously visited the church in Chapter 15 with Leif, and chosen the route to Fort Norden from there, and then visits the easternmost village in the next chapter with Leif as well.
Sleuf appears to be an especially pious, sedate, and virtuous individual, and his sound judgment often eases the minds of troubled people, like Amalda.
He joins Leif's cause to fulfill Claud's prophecy and to assist in preventing the destruction of the world by the Loptyrian Cult. After the war, he travels around the continent to spread the teachings of his religion, and contributes greatly to its eventual mainstream acceptance.
Staff - A

Despite joining at a rather low level, Sleuf can be immediately useful to have on the team as he has an A rank in staves. Essentially, this lets him have access to powerful staffs, such as Warp, Rescue, Rewarp, and Fortify without needing any prior training.
Between himself, Safy, and Tina, the two other playable Priests, Sleuf's defining trait is his high Skill, which ensures that he will have high accuracy when casting heal on his allies, or when inflicting status ailments on the enemy. He contrasts Tina by having better Skill, but less Luck and Speed, though their Magic stat is nearly equal, and he starts with a higher base. Compared to Safy, he has somewhat better durability, though they are otherwise nearly equal in terms of stats and utility.
Since Sleuf has the Blaggi scroll initially in his inventory, it is recommended to keep it there, if the player plans to use him, while he levels up to improve his statistical gains in Magic and Luck. His three movement stars give him a 15% chance to act twice in the same turn, which can be quite beneficial, such as if he missed with his staff earlier or to heal multiple people. Unlike Safy and Tina though, Sleuf does not have a unique staff that only he can use, while they are able to use Repair, Thief, and Unlock exclusively.
While Sleuf works best as a support unit, he may not be as good offensively as the other playable magic wielders are. He neither receives or gives any support bonuses to improve his performance or others' in battle (though characters with Charm or those wielding the King Sword can still support him); his Pursuit critical coefficient is 0, meaning he has no chance of executing a critical hit whenever on a second attack; also, his base Speed is low, requiring the player to raise it sufficiently enough for him to actually attack enemies twice in the first place. Furthermore, the low quantity of Lightning tomes available in the game for him to use makes it difficult for him to keep up his offense compared to Mages or Sisters, who have access to the more plentiful Fire, Wind, and Thunder tomes.
“L-Lord Claud... I'm sorry...I couldn't...fulfill your wishes...”
—Sleuf's death quote
“Prince Leif, the spirit of Blaggi will always be watching over you. Please have strength!”
—Sleuf's escape quote
Sleuf - A Blaggi Priest (ブラギの神官)
After the war, instead of returning to the Tower of Blaggi, Sleuf traveled around the continent spreading the teachings of Edda. Sleuf inspired other priests to do the same, and the Edda Church eventually became one of the leading religions of the continent.
- In the Fire Emblem Heroes Choose Your Legends poll, Sleuf ranked 776th with a total of 30 votes, coincidentally giving his placement the same number of his game of origin.
- Sleuf, in his recruitment quote, mentions 'The Light of Zwei'. This is never mentioned elsewhere and what it means (and its connection to the Deadlord Bovis, whose Japanese name is Zwei) is unknown.
