OSRS Leagues 6 Best Tier 8 Relics Guide
Tier 8 relics in OSRS Leagues 6 (Demonic Pacts) are the final power spike that defines how your build performs in high level combat. At this stage, your setup is already complete, so this choice is about finishing fights faster, increasing consistency, and pushing efficiency in bossing and Slayer.
Best Tier 8 Relic In OSRS Leagues 6
The best Tier 8 relic in OSRS Leagues 6 is Executioner because it allows you to instantly execute enemies below 20% health, dramatically speeding up boss kills and Slayer tasks.
Executioner gives you the Sage’s Axe, which can be thrown at targets once they drop below the threshold. This skips the final portion of every fight, which is often the slowest part.
Instead of grinding through the last chunk of health, you end fights early and move on immediately. Over multiple kills, this cuts down a significant amount of time.
Why Executioner Is The Strongest Final Pick
Executioner works in almost every combat situation and scales with how often you are fighting.
You are getting:
Instant execute at 20% health
Consistent finish speed across all enemies
No resource cost to use the ability
This is especially strong in bossing, where the final phase of a fight can take longer than expected. Skipping that portion speeds up kill cycles and increases efficiency.
It also works in areas like the Gauntlet, which adds even more value since it applies in content where efficiency is important.
How Executioner Changes Combat Flow
This relic smooths out fights rather than increasing raw damage.
Instead of:
Slowing down near the end of fights
Waiting for final hits to land
You:
Finish kills instantly at the threshold
Move directly into the next target
Maintain a consistent pace across encounters
This becomes more noticeable the longer you play, especially in Slayer or repeated boss runs.
When Minion Can Be Worth Picking
Minion adds a permanent damage source that follows you.
It provides:
A summoned companion dealing constant damage
AoE attacks in multi combat
Automatic looting for killed enemies
This can feel strong in multi combat situations or for more relaxed gameplay, since it adds damage without input.
The issue is that the damage is relatively small compared to your own output at this stage. It helps, but it does not change how quickly fights end in the same way Executioner does.
Where Flask of Fervour Fits
Flask of Fervour is a burst tool focused on survivability and damage.
It gives:
Full restore of health, prayer, and special attack
Temporary damage immunity
Area damage around your character
This is useful in difficult encounters or panic situations where you need to recover instantly.
It has a cooldown, though, which limits how often it can impact your gameplay compared to Executioner’s constant effect.

How Tier 8 Finalizes Your Build
This is the last layer of your build, so the focus is on efficiency rather than setup.
With Executioner, your combat becomes faster and more consistent across all content. Bosses, Slayer tasks, and general fights all benefit from shorter kill times.
Other options either add small passive damage or situational burst, but they do not impact every fight in the same consistent way.

Final Blurb
Executioner ends up feeling like a cleanup tool that removes the slowest part of combat. Once enemies drop low enough, fights just end, and you move on without delay.
At this point in the League, that consistency adds up more than anything else.
