1 Defence Pure Deep Dive

What is a 1 Defence Pure?

A pure is an account build that stays at 1 Defence to maintain a low combat level while maximizing offensive stats. This creates a massive advantage in PvP combat brackets.

Combat Level Calculation

Pures stay low combat by avoiding Defence XP:

• Base: 0.25 × (Defence + Hitpoints + Prayer/2)
• Melee: 0.325 × (Attack + Strength)
• Range/Mage: 0.325 × higher of (Ranged) or (Mage)

Common Pure Builds:

• 50 Attack Pure: Combat ~70 (Granite maul PKing)
• 60 Attack Pure: Combat ~80 (Dragon claws, better weapons)
• 75 Attack Pure: Combat ~90 (AGS, best gear)

Zerker Pure (45 Defence) Deep Dive

What is a Zerker?

A Zerker pure maintains exactly 45 Defence to wear Berserker helm and Fremennik armor while still maintaining a lower-than-main combat level. It's the "hybrid" PvP/PvM account type.

The 45 Defence Formula

You must reach EXACTLY 45 Defence via quests only:

• Nature Spirit: 2,000 XP
• Darkness of Hallowvale: 7,000 XP (requires 33 Defence)
• Fremennik Exiles: 15,000 XP (requires 40 Defence)
• Between a Rock: 5,000 XP
• Heroes' Quest: 3,075 XP
• Elemental Workshop II: 5,000 XP
• Dragon Slayer: 18,650 XP
• Olaf's Quest: 12,000 XP
• Devious Minds: 6,500 XP
• Fremennik Isles: 16,000 XP
• Total XP needed: 101,333 XP = exactly level 45

⚠️ DO NOT TRAIN 1 SINGLE DEFENCE XP OUTSIDE QUESTS! ⚠️

Zerker Pure Advantages

PvP Versatility:

• Strong in mid-level combat brackets (90-105)
• Berserker helm (+3 Strength bonus)
• Fremennik armor (good defence + attack bonus)
• Can use all PK weapons
• Barrows gloves
• Vengeance (Lunar Diplomacy)

Some PvM Access:

• Can do most bosses (with more effort)

• Quest cape is possible (careful planning)

Better Gear Options:

• Helm of neitiznot
• Fremennik armor
• Fighter torso

Disadvantages ❌

Extremely Precise Building:

• Must reach EXACTLY 101,333 Defence XP
• ONE EXTRA POINT = zerker is ruined forever
• Can't accidentally train Defence (ever)
• Can't do many Defence quests
• Must plan quest order perfectly

Quest Restrictions (less than pure, but still limited):

• Can't do King's Ransom (+33,000 Def XP = ruins zerker)
• Can't do Monkey Madness II (ironman BiS locked)
• Check EVERY quest for Defence rewards
• 40+ quests still restricted

PvM Limitations (better than pure, worse than main):

• Still can't wear best gear (need 65-75 Def)
• Bandos: ❌ (65 Def)
• Armadyl: ❌ (70 Def)
• Raids 3 (ToA): Possible but harder
• Can't tank as well as mains
• Higher supply costs

Prayer Decision:

• 52 Prayer (Smite) for pure PKing
• 74 Prayer (Rigour/Augury) for PvM
• Going 74+ raises combat ~3-4 levels

Permanent Risk:

• Ruining your zerker is EASY
• Wrong quest = too much Def XP = dead zerker
• Must track XP constantly
• Can't recover from mistakes

Best For:

• Experienced players who want PvP + some PvM
• Those who LOVE planning/optimization
• Players who can follow guides precisely
• Hybrid PvP/PvM playstyle

Starter Path Recommendations

Zerker → Main: ✅ YES

• Once you have 2+ Defence, can't be pure
• PERMANENT

Verdict: Always go Pure → Zerker → Main progression. You can "upgrade" but never downgrade.

FAQ

Is a 1 Defence pure better than a zerker in PvP?

For PvP, the 1 Defence pure has the biggest bracket advantage, fighting opponents 20-30 combat levels higher. Zerkers are strong in the 90-105 bracket with Berserker helm and Vengeance, but pures dominate their own bracket more decisively.

What Defence level does a zerker pure have?

A zerker pure must have exactly 45 Defence, reached through quests only for a total of 101,333 XP. Training even one extra Defence point outside quests permanently ruins the build.

How long does it take to build a 1 Defence pure?

Building a 1 Defence pure takes roughly 50-100 hours, making it the fastest account build to complete. A zerker takes 100-200 hours, while maxing a main takes 2,000 hours or more.

Can you turn a pure into a main account?

Yes. You can always add Defence to upgrade a pure into a zerker or main, but you can never remove Defence levels. Once an account has 2+ Defence it can no longer be a pure, and 46+ Defence means it cannot be a zerker.

What is the best account build for PvM?

A main account is best for PvM, with full access to all bosses, raids, and gear. Zerkers can do most bosses but harder with restricted gear, while 1 Defence pures are limited to safespotting and have almost no PvM content.

How much does it cost to build a main account?

A main account costs 100M-1B+ to build, with full Best-in-Slot gear potentially running 2-5B. By comparison, a 1 Defence pure costs only 40-90M and a zerker 100-200M.

Conclusion

The Simple Answer:

• New players: Main account (can always make pure later)
• PvP lovers: 1 Defence Pure
• Want both PvP + PvM: Zerker (hard mode)
• Want everything: Main account

Most Popular Choice: Main account (80%+ of players)

Most Exciting: Pure accounts (PvP dominance)

Hardest: Zerker (requires perfect execution)

Best Long-Term: Main account (unlimited content)

My Recommendation: Start with a main, learn the game, make money. If you love PvP, make a pure as your second account and fund it with your main. Best of both worlds!

Remember: You can always "upgrade" from Pure → Zerker → Main, but you can NEVER go backwards. Choose carefully!

Good luck with your account building! ⚔️🛡️
