How to Use the Party Role Survival Rate Calculator
Before heading into a raid or dungeon, it's natural to want a rough sense of whether your current composition can actually survive it. This calculator estimates your party's overall survival rate using a simple additive model — multiplying the number of players in each role by that role's survival contribution and adding it all up. It starts from a 20% baseline survival rate and builds from there based on your role counts and contributions.
Tanks contribute by absorbing damage, healers by restoring health, and DPS by ending fights faster and shortening overall exposure — each in its own way. Since these contributions vary a lot depending on content difficulty and player skill, adjusting the values based on your own party's actual clear experience gives the most accurate result.
Keep in mind this is a simplified reference estimate, not a real combat log or probability model. If the survival rate comes out low, consider rebalancing your composition or improving individual role execution before diving in.
Even with the same total headcount, a party stacked with DPS but no tank or healer tends to show a noticeably lower survival rate. For tougher content, securing solid tank and healer coverage usually raises overall survival more effectively than simply adding more DPS.
Frequently Asked Questions
With no fixed formula, try tanks around 15-20%, healers around 15-25%, and DPS around 5-10% as starting points, then adjust them to match your party's actual clear results.
No, this calculator caps the survival rate at 99% no matter how strong the composition is, since any party can always face unpredictable factors that lead to a wipe.
