In OSRS and other RPGs, players often debate whether average DPS or real-time kill speed is the more important metric. While DPS calculators give you neat numbers for sustained damage, actual fights include mechanics, downtime, and player input that change the outcome. So, which should you prioritize: the theory or the reality?
What Is Average DPS?
Average DPS (damage per second) is the theoretical sustained output of your setup.
- Formula: max hit × accuracy × attack speed ÷ time (ticks).
- Strengths: Great for comparing weapons or builds in controlled conditions.
- Weaknesses: Doesn’t reflect real fight interruptions like movement, prayer switching, or boss mechanics.
👉 If you want to experiment with setups, the OSRS DPS Calculator is the best way to model sustained output.
What Is Real-Time Kill Speed?
Real-time kill speed is the actual time it takes to finish a kill from start to finish.
- Affected by:
- Boss mechanics (phases, invulnerability, movement).
- Burst damage (special attacks, ruby bolt procs).
- Player performance (gear switches, prayer flicks, reaction time).
- Why it matters: It reflects how fast you actually clear content, earn GP, or gain XP.
For boss-specific encounters, you can simulate setups with the OSRS Boss DPS Calculator. To ensure your setup is balanced across all styles, use the OSRS Average DPS Calculator for multi-attack evaluations.
DPS vs Kill Speed: Practical Example
| Setup | Average DPS | Real Kill Speed | Notes |
|---|---|---|---|
| Bowfa at Vorkath | ~95 | ~3:00 per kill | Consistent sustained DPS |
| DHCB + Ruby bolts | ~85 | ~2:30 per kill | Ruby procs reduce fight length |
| Zulrah Hybrid | ~80 | ~2:45 per kill | Gear switching cuts downtime |
You can also compare hybrid and burst setups using the Special Attack DPS Calculator to see how specs affect real kill times.
