“Lester, if I were you I'd be a bit more concerned about your sister. Lana might be out here fighting for all you know. Oifey, we need to hurry. I'm worried about Sir Seliph!”
—Delmud
In Genealogy of the Holy War, Delmud is a member of Seliph's army and trains alongside Oifey. In Thracia 776, he joins Leif's army to protect his sister. He is able to wield the Beo Sword in this game, hinting that his canon father is most probably Beowolf.
Coming with the Charisma skill, Delmud will always be able to support your other units, but if his father does not pass down the Pursuit skill, he will not be an ideal fighter.
Beowolf, Azel, and Finn are considered to be the best fathers for Delmud, but he will do just fine as long as he inherits the Pursuit skill. Despite the fact that Azel is of the Mage class, Delmud's strength will not suffer any repercussions, as this is thankfully offset by Raquesis's minor Hezul holy blood. Additionally, Azel's minor Fala blood will enable Delmud to be a formidable unit with any magic sword he wields.
Dew can make a good father, bestowing great strength, other great growths, and good base stats. However he may not be able to pass down the pursuit skill unless he is promoted. There would also not be much point to passing down the bargain skill to Delmud because money should not be a problem for him. Alec can provide similar stats, but will not be as good.
Think of Delumd as a weaker, more support oriented version of Felgus. He has higher movement, and stats almost comparable to Felgus at similar levels. Regardless of which, he still makes for a useful unit, with slightly above average stats for his level. However, as he joins Leif's army relatively late into the game, he will end up being outclassed by many other units that the player has control of, and will often be completely overlooked. He will end up being an above average fighter, and when coupled with the Beo Sword, will be capable of taking out quite a number of enemies on his own. Furthermore, he will be able to provide substantial bonuses to other units within two spaces, further enhancing his usefulness as a unit on the battlefield.
