Old School RuneScape Guide: The Giants' Foundry
What is the Giants' Foundry?
The Giants' Foundry is a large-scale group boss activity where players fight against waves of powerful giants and other creatures inside a dynamic, puzzle-oriented dungeon. Designed for high-level players, the Foundry requires strategic planning, communication, and skill usage. It is accessible via the Foundry entrance in the Fremennik Province, but players must meet certain requirements to participate.
Key aspects of the Foundry include:
Team-Based Combat: Designed for groups of 3-5 players.
Wave Mechanics: Multiple waves of enemies, each increasing in difficulty.
Environmental Challenges: Interactive elements like traps, barricades, and puzzles that require coordination.
Boss Battles: Each run culminates in a fight against a powerful giant boss with unique abilities.
Rewards and Loot: High-level drops including rare weapons, armor, crafting materials, and OSRS gold.
Requirements and Preparation
Skill Requirements
Before entering the Giants' Foundry, players should meet certain skill benchmarks:
Combat Level: Recommended 90+ combat for solo competence or 100+ for team efficiency.
Prayer: Level 70+ is highly recommended for protection prayers and overheads.
Ranged/Magic/Strength/Attack: Depending on your combat style, at least 70+ in your primary offensive skill is recommended.
Agility and Constitution: Useful for maneuvering traps and avoiding environmental hazards.
Gear Recommendations
The Giants' Foundry features enemies with high defense and damage output. Gear selection is vital:
Melee Setup: High-tier weapons like Abyssal Whip, Scythe of Vitur, or Bludgeon. Tank armor with Torva or Bandos sets is recommended.
Ranged Setup: Twisted Bow, Blowpipe, or Rune Crossbow with Armadyl or Karil's armor.
Magic Setup: Sanguinesti Staff or Trident of the Swamp, paired with Ancestral or Ahrim's robes.
Accessories: Amulet of Fury, Berserker Ring (i), or Arcane Prayer Bonuses depending on style.
Inventory: Potions (Saradomin Brews, Super Restores), high-healing food, teleportation tablets, and stamina potions.
Team Composition
While some skilled players can tackle parts solo, the Giants' Foundry is optimized for a coordinated team:
Tank: Absorbs damage, controls enemy focus, and manages environmental hazards.
DPS (Damage Dealers): High damage output using melee, magic, or ranged. DPS players focus on eliminating waves quickly.
Support/Healer: Provides healing, debuffs enemies, or buffs teammates. May also handle puzzle-solving mechanics.
Understanding the Mechanics
The Giants' Foundry is more than a simple boss fight. Each wave introduces new mechanics and environmental challenges.
Wave System
Wave 1-3: Standard giants and minor elemental foes. Focus on positioning and damage prioritization.
Wave 4-6: Adds mini-bosses with special abilities. Use crowd control spells and prayers effectively.
Wave 7-9: Environmental hazards become prominent. Some areas may collapse, requiring agility and careful movement.
Final Wave: The main boss appears with a combination of AoE attacks, powerful single-target abilities, and unique mechanics such as summoning minions or environmental traps.
Boss Mechanics
Each boss in the Giants' Foundry has unique attacks:
AoE Sweeps: Areas of effect that deal high damage. Tanks should absorb or lure enemies while DPS targets other threats.
Enrage Phases: Bosses may become stronger at 50% HP or after summoning minions. Timing cooldowns and using food efficiently is critical.
Environmental Interactions: Some bosses may manipulate the room layout or trigger traps. Team communication ensures survival.
Puzzle Elements
Some waves feature interactive puzzles like:
Valve Activation: Players must work together to open doors or disable barriers.
Lever Pulls: Requires timed activation to prevent waves from overwhelming the team.
Trap Navigation: Spikes, fire, or collapsing platforms necessitate agility and careful positioning.
Successfully solving these puzzles can reduce damage taken, prevent waves from spawning early, or unlock additional loot.
Combat Strategies
General Tips
Focus Fire: Assign priority targets to prevent being overwhelmed.
Prayer Switching: Constantly switch prayers based on enemy attack styles.
Positioning: Avoid being surrounded; use the room layout for advantage.
Cooldown Management: Use high-damage abilities strategically rather than spamming.
Communication: If in a team, clearly communicate movements, mechanics, and enemy priorities.
Solo Strategies
While challenging, experienced players can handle lower waves solo:
Use high-damage weapons and potions to accelerate wave clearing. You can buy OSRS GP to get if you don't have them.
Focus on mob control to prevent getting surrounded.
Exploit safe zones in the environment to reduce incoming damage.
Consider familiar or minion-based combat styles for additional DPS or tanking.
Rewards and Loot
The Giants' Foundry offers attractive rewards for players willing to brave its challenges:
Rare Weapons and Armor: Including high-tier PvM items not obtainable elsewhere.
Crafting Materials: Used to upgrade weapons, create new gear, or enhance potions.
Experience Points: Combat, prayer, and other relevant skill XP.
Cosmetic Unlocks: Unique skins or capes for achievement hunters.
Foundry Tokens: Can be exchanged for special rewards or items.
The loot is scaled based on wave completion and efficiency, encouraging players to complete higher waves for maximum reward.
Conclusion
The Giants' Foundry in Old School RuneScape is a complex, rewarding, and highly strategic activity. Unlike standard PvM content, it combines combat, puzzle-solving, and teamwork to create a challenging experience suitable for high-level players.

Whether you aim for the thrill of the fight, the riches, or the lore, the Giants' Foundry provides a unique and immersive adventure that sets it apart from other activities in Old School RuneScape.
