How to Beat Viconia DeVir in BG3: Complete House of Grief Boss Guide
Complete BG3 House of Grief boss guide. How to beat Viconia DeVir, navigate the Sharran enclave, save Shadowheart's parents, and the best strategy for Darkness spam.
The House of Grief
Located in the northwestern Lower City. Enter and speak to the receptionist. Pass a persuasion check or fight your way downstairs. Activate the altar with a gem to descend into the Sharran enclave.
Viconia DeVir Boss Strategy
Viconia is a high-level Cleric of Shar with 12+ Sharran acolytes. The arena is dark and enemies spam Darkness.
The Darkness Problem
Sharrans cast Darkness everywhere. Your party can’t see, has Disadvantage on attacks, and can’t target enemies with ranged spells.
Solutions to Darkness
| Method | How It Works |
|---|---|
| Daylight spell | Dispels Darkness in a 60ft radius. Shadowheart can cast this despite being former Sharran. |
| Devil’s Sight | Warlock invocation. See through magical darkness. |
| Ranged AoE | Fireball, Ice Storm, Spirit Guardians don’t need direct targeting. |
| Retreat to choke point | Pull back to the stairs where Darkness can’t fully cover the area. |
Strategy
- Cast Daylight immediately — it’s the fight-winner
- Spirit Guardians on Shadowheart and walk through the Sharrans
- Focus Viconia first — she’s the healer and caster
- Kill the 2-3 elite Sharrans (Dark Justiciars) next
- Clean up the Novices last (they’re weak individually)
After the Fight
Viconia surrenders. Shadowheart confronts her about her parents. Viconia reveals their location — they’re held in magical stasis nearby. Free them and make your choice.
Frequently Asked Questions
Should I save Shadowheart's parents?
It's a difficult choice. Saving them means they live but suffer chronic pain from Shar's curse, and Shadowheart experiences flare-ups. Letting them go means they die but are freed from Shar's torment. There's no wrong choice — both are narratively satisfying.
