A very low cost questing and healing hero with a side order of readying.
Laekna has a very efficient stat line with 3 willpower and 3 hit points for just 6 threat. That is great for fitting in with the relatively high threat cost of the other Beorning heros Beorn and Grimbeorn. Given her solid 3 willpower and the combat focus of other Beornings, she slots right into dedicated questing hero.
Readying then become essential to use her healing ability. There are not many in sphere options with Lore other than Leather Boots. Leather Boots isn’t reliable since the player is at the mercy of the encounter deck revealing a location. Spirit has the better sphere for readying with Unexpected Courage, Miruvor, Spare and Hood Cloak, and Westfold Horse-breaker. Leadership’s Cram and Naith Guide could also work for Laekna to quest and heal. There aren’t any Tactics options that’d work for her in the FFG card pool, but Beorn created Honey Cake that can provide at least 1 instance of readying.
Playing more healing with Laekna increases the consistency for her ability to ready her target. Fortunately there are many great options for this to choose from in Lore.
The best targets for her heal and readying are characters multiple good stats and/or exhaust abilities. This works great for her fellow Beornings, Grimbeorn the Old (both hero and ally versions) with his 3 attack and defense and Honaboern that can have 3 willpower and 3 attack when they have at least 2 damage.
The ability isn’t restricted to Beornings letting her target many powerful heroes and ally cards with 3+ in 2 or more stats like every version of Gandalf, Glorfindel, Elrond, Gildor, Amarthuil, Thorin Oakensheild, and Tactics Theoden. Then there are those too with exhaust abilities that can be leveraged as well like Gildor ally, Elrond with Vilya, Beravor, Honour Guard, and more.
Laekna I can see her slot into a lot of decks because is just so very efficient with a low threat cost. That is just as a dedicated questing hero with her healing ability just as a bonus. Lore doesn’t have a lot of high willpower heroes much less a low threat one. Victory Display decks could have a dedicated quester and still run at Secrecy pretty easily with her. Getting her readying preferably with Unexpected Courage to heal and possibly ready a character in addition to questing would be amazing. When I played her in a Beorning deck, her healing was needed but often couldn’t spare her because her willpower was needed. Make sure to play her with some readying available or ways to redirect damage to herself. Then she can at least heal herself and ready to quest.
