Super Defence (4) OSRS Potion – Effects, Uses, and Stats

The Super Defence (4) is a core consumable for players looking to improve survivability in Old School RuneScape. When players talk about super defence OSRS, they point to the reliable Defence boost that helps tanks, questers, and boss hunters hold the line in heavy fights. With four sips per vial, it offers steady value across long trips and protects gear setups that depend on Defence calculations in combat. This guide covers how the potion works, when to drink it, and how to source it for consistent play.

What is Super Defence

Super def is a strengthened Defence potion that sits above the basic Defence potion tier. The Super Defence (4) version holds four doses that each provide a temporary buff to your Defence level.

Each dose increases Defence by +5 and 15% of your base Defence level (rounded down). The potion only boosts your Defence level and does not change any equipment stats or bonuses. It also cannot be used to equip items you otherwise do not meet the requirements.

It is widely used across Slayer tasks, boss runs, and dangerous quests where incoming damage adds up fast. 

Key Features

Players choose the super defence potion OSRS for several practical reasons. 

1. Four-dose economy reduces banking trips.
2. Boost applies to hit chance calculations for all combat styles.
3. Pairs cleanly with combat potions and prayers.
4. Easy to buy on the Grand Exchange.
5. Available as drops from certain high-level monsters and PvM activities.

Below is a quick reference table for the standard Super Defence (4).

Effects and Usage

Each sip increases Defence and reduces the chance of incoming attacks landing successfully. While it does not directly reduce damage taken, higher Defence causes enemies to hit less often over time, resulting in fewer food uses and longer trips.

Some players use the OSRS super defence mix for short content or budget runs, though the four-dose vial remains the mainstay for most PvM. For team PvM, drinking before the opening damage phase gives immediate defensive stability. Solo content benefits as well, especially in areas with consistent incoming combat pressure.

Common use cases

• Bossing where sustained damage matters.
• Slayer tasks with aggressive monsters.
• Quest fights that lock you in an arena.
• PvP scenarios that hinge on tanking and escape.

Magic defence in OSRS partially scales from Defence (30% Defence, 70% Magic), making this potion useful even against magical attacks when combined with proper gear and prayer management.

Creation

Many players wonder how to make super defence potion OSRS from scratch. All you need is to combine a Cadantine potio with white berries. The process requires 66 Herblore and standard mixing steps at a potion interface.

Players completing the elite clue step, requiring a Super Defence potion, often keep ingredients banked to finish quickly.

Variants and Combinations

The OSRS super defence potion can be decanted into smaller doses, or you can seek out super defence mix OSRS for lower-cost runs. For divine effects, the OSRS divine super defence potion locks the boost in place at the cost of losing Hitpoints over time.

Many players combine Defence boosts with offensive potions and prayers to balance survivability with damage output.

Acquisition

Most players grab their super defence pot OSRS from the Grand Exchange for speed. Crafting suits iron accounts and anyone levelling Herblore. PvM players can obtain them from certain bosses and high-level monsters that drop combat supplies.

Market Information

The OSRS super defence potion ge price shifts with supply from PvM drops and demand from bossing activity. Tracking historical prices helps with bulk purchases, and decanting often lowers the cost per dose when buying in volume.

Prices fluctuate based on updates, supply changes, and Grand Exchange trading activity rather than formal "seasons".

Trivia

The Super Defence potion improves survivability by reducing hit chance, not damage taken directly.

Whether you buy it, brew it, or loot it, the Super Defence (4) remains a dependable defensive tool for any account that values longer trips and safer fights. Drink it early, refresh it as it degrades, and let Defence carry you through tougher encounters.
