This is an annoying gank fight that can be cheesed by using poison and toxic. As shown in the first video below, run to a pillar and stand there, wait for Halflight to spawn, equip the Storyteller's Staff and use its weapon art to poison Halflight. Once Halflight is poisoned, cast Toxic Mist. Refer to the following videos for various cheese strategies.
Halflight NG+32 Storyteller's Staff & toxic, Dark Souls III
Dark Souls 3 - Halflight Easy Cheese Kill - Storyteller's Staff
Dark Souls 3 Halflight no aggro easy kill
Depending on far you have progressed with Lapp's questline, you can summon him as Unbreakable Patches to help you distract one enemy while you concentrate on the other enemy. No matter what you do, always defeat the Painting Guardian (during both phases) as quickly as possible to prevent him from healing Halflight.
