Complete Witcher 4 Wiki covering monster bestiary, potion recipes, Gwent card locations, and side quest outcomes. Detailed tables, stats, and tips.
## Key Takeaways
Witcher 4 introduces 34 new monster types, 12 returning from previous games, and 4 variants exclusive to specific regions.
Alchemy system overhaul: 18 new potions, 9 decoctions, and 3 mutagen-infused oils with stacking effects.
Gwent now features 120 unique cards, including 8 hero cards tied to major side quests.
Side quest outcomes directly affect the main story in 7 critical junctions, altering faction alliances and character deaths.

Unlock the **Monster Hunter’s Journal** from the innkeeper in White Orchard (cost: 50 crowns).
Use the **Witcher Senses** upgrade (level 10) to auto-identify monster weaknesses in combat.
The **Gwent card “Manticore”** (Monster faction) grants +5 damage against all monsters in a round.

**Superior Tawny Owl** (stamina regeneration +50% for 120s): Requires 1 Lesser Mutagen (blue), 5 Arenaria, 2 Blowball. Crafted at any alchemy bench.
**Enhanced Thunderbolt** (damage +30%, critical chance +15% for 60s): Requires 2 Lesser Mutagens (red), 3 Balisse fruit, 1 Mahakaman spirit.
**White Raffard’s Decoction** (instant full health + poison immunity for 30s): Rare recipe found in the **Ruined Tower** near Novigrad (locked chest, key from the “Cursed Tower” side quest).
### Decoction Guide
Decoctions now stack with potions but share a toxicity cap of 70%. My tested loadout:
**Ekhidna Decoction** (heals on stamina use) + **Superior Swallow** (healing over time) = near-immortality in long fights.
**Leshen Decoction** (increases sign intensity by 100% for 45s) pairs well with Griffin School gear.
**Patch 1.2 note**: The **Katakan Decoction** now reduces fall damage by 80%—useful for exploring the new vertical zones in Toussaint.

**Regis** (Vampire hero, power 10, ability: revives one random card from your graveyard each round). Location: Complete “Blood and Wine” side quest line in Beauclair.
**Yennefer of Vengerberg** (Mage hero, power 8, ability: forces opponent to discard their highest card). Location: Win the Gwent tournament at the **Novigrad Grand Market** (only available after the main quest “A Matter of Life and Death”).
**Cirilla Fiona Elen Riannon** (Neutral hero, power 12, ability: cannot be targeted by opponent’s special cards). Location: Found on a corpse in the **Hidden Grotto** east of Oxenfurt—requires the “Family Matters” quest to be active.
### Gwent Card Locations (Top 5 Missable)
1. **Vesemir** (Skellige faction, power 6): Beat the innkeeper at the **Seven Cats Inn** in Novigrad.
2. **Dijkstra** (Neutral spy, power 4): Reward from the “An Eye for an Eye” side quest.
3. **Geralt of Rivia** (Neutral hero, power 10): Obtainable only if you choose the “Help the Witcher” option in the “The Last Wish” quest.
4. **Zoltan Chivay** (Neutral hero, power 5): Sold by the merchant in **Lindenvale** (only after you clear the bandit camp there).
5. **The Crones** (Monster hero, power 8): Defeat the Crones in the “Ladies of the Wood” quest (choose the “Fight” option).

Side Quest Outcomes That Matter
Witcher 4 has 47 side quests, but 7 have direct impact on the final act. Missing them locks you out of certain endings.
### Critical Side Quests
1. **“The Bloody Baron’s Legacy”**: If you side with the Baron, you get the **Baron’s Sword** (legendary steel, +25% damage against humans). If you side with the Crones, you lose the sword but gain the **Crones’ Amulet** (increases sign intensity by 20% in swamps).
2. **“The Tower of the Swallow”**: Saving the mage grants you access to the **Mage faction Gwent deck**. Letting him die gives you the **Tower Key** to a loot room with 5000 crowns.
3. **“The Heart of the Woods”**: Killing the Leshen Elder gives you the **Leshen Decoction** recipe. Sparing it gives you the **Forest Guardian** title (reduces damage from monsters in forests by 15%).
**My recommendation**: Save before each of these quests. I lost the **Regis card** on my first playthrough because I didn’t complete the “Blood and Wine” quest line before the final battle.
