As an action, Seraphina can open her awareness to detect the presence of strong celestial, fiendish, or undead forces. Until the end of her next turn, she knows the location and type of any such creature within 60 feet that is not behind total cover. She can use this feature three times per long rest. She can also detect the presence of consecrated or desecrated places or objects, though this requires an action and provides no further information.

Seraphina has a pool of restorative power that replenishes when she finishes a long rest. The pool can restore a total of 10 hit points. As an action, she can touch a creature and draw power from the pool to restore any number of hit points up to the amount remaining. Alternatively, she can spend 5 hit points from the pool to cure one disease or neutralize one poison affecting the target. This feature has no effect on constructs or undead.

Seraphina places herself between an ally and danger, using her shield and disciplined footwork to hold the line.

Seraphina channels a prepared spell slot through a successful melee strike, releasing a burst of searing celestial radiance.

Seraphina adopts the Defense fighting style, gaining a +1 bonus to AC while wearing armor.

Seraphina can cast prepared paladin spells using Charisma as her spellcasting ability. She can use a holy symbol as a spellcasting focus. She has two 1st-level spell slots.

When Seraphina hits a creature with a melee weapon attack, she can expend one spell slot to deal radiant damage in addition to the weapon's damage. The extra damage is 2d8 for a 1st-level slot, plus 1d8 for each spell slot level above 1st, to a maximum of 5d8. The damage increases by 1d8 against undead or fiends.

Seraphina can reliably find the local military organizations, mercenary companies, and veterans in any settlement. Such groups recognize her authority as a fellow soldier and may provide shelter, information, or limited assistance, depending on the circumstances.
