Ansur — Wyrmway Dragon
Location: Wyrmway, beneath Wyrm’s Rock Fortress. Requires completing Wyll’s questline and passing the Wyrmway puzzle trials (4 chambers).
Pre-Fight Checklist
- Long rest before entering the Wyrmway chambers.
- Heroes’ Feast + Aid — massive HP buffs. Ansur hits VERY hard.
- Elixir of Lightning Resistance on everyone — Ansur’s main damage is Lightning. Storm Sorc already has lightning resistance (Heart of the Storm at L6).
- Elixir of Vigilance on everyone.
- Bring Counterspell — Ansur has devastating AoE spells.
- Stoneskin on Lae’zel (Shadowheart pre-cast).
Boss Mechanics
| Mechanic | Detail |
|---|---|
| Ansur | Undead dragon, ~400 HP on Honour Mode. Resistant to Lightning, immune to Poison/Necrotic. Vulnerable to nothing — pure raw damage needed. |
| Lightning Breath | Massive cone AoE, 10d10 Lightning, DEX save for half. Hits everyone in a 30m cone. Spread out fan-shaped. |
| Storm Clouds | Ansur summons storm clouds that deal periodic Lightning damage. Move out of them. |
| Gathering Power | Ansur channels for 1 turn, gaining energy. Next turn: massive nova (point-blank AoE). HIDE behind the ice crystals or run to the edge of the arena. |
| Legendary Action: Wing Buffet | Knocks everyone back + Prone. STR save. |
| Hoarding Energy | In Honour Mode, Ansur stores energy each turn he’s not hit with Radiant damage. |
Phase 1 — Dragon Aerial
Ansur flies around the arena, using Lightning Breath and summoning storms.
Tactics
| Tactic | Detail |
|---|---|
| Spread out | Lightning Breath is a cone. Everyone at different angles — if you’re all in front, you all die. |
| Radiant damage | Prevents Ansur from Hoarding Energy (Honour Mode only). Spirit Guardians (Radiant), Blood of Lathander, Divine Smite. |
| Counterspell | Counterspell his Lightning Breath if you can — it’s a spell, not a natural ability (verified on bg3.wiki: Ansur’s breath is a spell-like, Counterspell works). |
| Stay out of clouds | Move out of the electrified zones immediately. |
Party Assignment
| Build | Role |
|---|---|
| Storm Sorc | Counterspell Lightning Breath. Lightning Bolt does reduced damage (resistance) — use Magic Missile / Disintegrate instead. |
| Wild Magic Sorc | Disintegrate. Wall of Fire if Ansur lands. |
| Shadowheart | Spirit Guardians (Radiant) — prevents Hoarding Energy. Healing Word on anyone taking breath damage. |
| Bardadin | Divine Smite (highest slots, Radiant). Aura of Protection for saves. |
| Lae’zel | GWM nova when Ansur lands. Action Surge. Radiant damage if possible (Silver Sword bonus). |
| Astarion | Sharpshooter. Arrow of Dragon Slaying (double damage vs dragons). |
| Throwzerker | Enraged Throw when Ansur lands (auto-prone). |
Phase 2 — Gathering Power (Nova)
Ansur lands and channels for 1 turn. The UI prompts: “Ansur is gathering power…”
Survival
- Do NOT attack him — focus on survival.
- Hide behind ice crystals — the arena spawns large ice formations. They block the nova damage. Everyone get behind one.
- Run to the arena edge — if you can’t reach a crystal, run as far away as possible. The nova is centered on Ansur.
- Globe of Invulnerability — cast it behind a crystal and wait out the nova.
After the nova, Ansur is briefly vulnerable. Dump everything.
Honour Mode Specifics
- Hoarding Energy is lethal. Ansur gains +1 to damage and attack rolls per turn of stored energy. Without Radiant damage every round, he becomes unstoppable by turn 5-6. Always have someone dealing Radiant (Shadowheart Spirit Guardians, Bardadin Smites, Blood of Lathander).
- Lightning Breath can TPK. In Honour Mode, it’s 12d10 Lightning instead of 10d10. One breath on a clustered party = wipe. Spread out, Counterspell, Lightning Resistance elixirs.
- Gathering Power nova is also buffed in Honour Mode. Don’t try to tank it — ALWAYS hide.
Post-Fight
- Loot Ansur: Balduran’s Giantslayer (legendary greatsword, double STR mod, Giant Form).
- Altar behind Ansur: Helm of Balduran (legendary helmet, immune to crits/stun, heal 2 HP/turn, +1 AC/saves).
- Wyll’s questline concludes — he faces the truth about his father and Ansur.
