Ye Wei'an had Lina deliver the finishing blows to the prisoners today for this very purpose.
Although finishing off enemies barely earned any experience, even a single point was enough to unlock a class level for an ordinary person.
[Alexandrina Sebastian, Human, Lv. 1 Commoner (3/0), Strength 12, Dexterity 9, Constitution 11, Intelligence 12, Wisdom 10, Charisma 13]
Lina's only ability score above 13 was Charisma. Her class options were Bard, Paladin, Sorcerer, and Warlock.
Considering Lina's usual duties and the army's current lack of healers, Ye Wei'an chose Bard for her.
A level 1 Bard could choose two cantrips and four 1st-level spells, gain proficiency in three skills, and acquire the ability to inspire others.
For her cantrips, Ye Wei'an chose [Vicious Mockery] and [Prestidigitation].
The former let her hurt others through her words—she could literally wound them with her words.
The latter would make her usual work easier.
For her 1st-level spells, Ye Wei'an chose [Heroism], [Tasha's Hideous Laughter], [Healing Word], and [Unseen Servant].
[Heroism]: You touch a willing creature, filling it with courage and granting it temporary hit points.
[Tasha's Hideous Laughter]: The target laughs uncontrollably, unable to stand or take actions.
[Healing Word]: You choose a creature you can see within spell range and restore its hit points.
[Unseen Servant]: You create an invisible, mindless, shapeless servant that you can command to perform simple tasks.
Next came her race. The [Human] race granted a +1 bonus to two ability scores and an Origin feat.
Ye Wei'an chose +1 to Charisma and Strength, and selected [Skilled] as her Origin feat.
[Skilled]: You gain proficiency in three skills or tools of your choice.
Ye Wei'an intended Lina to be his head maid and personal secretary, a position that certainly called for her to master a few more crafts.
