How to Recruit Ekundayo
Ekundayo can be found at the Ruined Watchtower during the Troll Trouble questline in Chapter 2.
A ranger in search of vengeance, Ekundayo will arrive in the Stolen Lands in the wake of the creatures he hunts - Trolls. He's a man of few words and even less joy, beingly morose and dedicated to his obsession. After you prove your worth to him, he'll join you, but be warned, he won't react well to any deals with the beasts that plague the lands of men. Unlike many characters, he joins the party later, starting out as a 5th level Ranger.
Despite his brooding, Ekundayo's talent as an archer is second-to-none, with an impressively high Dexterity score, and enough Strength to allow him to participlate in melee... or better yet, add more damage to his ranged attacks via a composite bow. His Constitution isn't poor, either, giving him some staying power should he be required to engage in melee. His Wisdom may be an issue when he starts gaining Divine magics, but he'll never be much of a spellcaster anyways.
As far as skills go, Ekundayo's high Dexterity gives him a great natural bonus to Stealth. He doesn't have Sneak Attack, however, meaning he'll mostly be useful in a scouting role, although you can use him to keep your camp hidden and avoid encounters. Considering his high Dexterity, he's probably best off in light armor. That matched with his decent Strength score also makes him a good candidate for Athletics. His Wisdom isn't great, so he won't be spectacular at Lore (Nature) or Perception checks, although he starts out with points in both, but unless you want to boost his Mobility, you might as well just keep dropping points into the skills he starts invested in.
If you want a top-tier archer, you need look no further than Ekundayo. His versatility may tempt you into working him into a melee role, but he's best used at range, meaning you should keep your best armor and defensive items for your tanks. If needed, have Ekundayo equip a melee weapon with reach (such as a longspear) so he can participate in melee when arrows aren't advantageous.
