Enter your roster size and clan-average level and gear score to estimate aggregate war power, then read your war-readiness tier before the next Blood Moon siege.

Power on the battlefield of Duskmaw is never one number on a scoreboard — it is the sum of what every hunter, thrall and pack-runner brings when the keep gates buckle. This calculator models that sum. Each member contributes a base drawn from their level and their gear score, and then the whole clan earns a coordination bonus for being able to rotate, res and stack buffs across a full war party.
New war-leaders over-recruit. They fill the roster with fresh converts and wonder why a leaner rival still takes their keep. The math is blunt: a single legendary weapon can add more effective power than three green-geared recruits, and only twenty bodies fit a siege lane anyway. If your tier feels stuck, push gear score before you push invites.
Bigger clans do fight better — up to a point. Past roughly forty members the coordination bonus flattens, because a single keep cannot use more than a couple of rotating defence squads at once. Use the overflow to open a second front or to bench your weakest twenty, not to pad a single siege.
When you are ready to turn this number into a plan, read the clan war guide for siege timing and lane assignments, or study the full clan system for perks, treasury and rank structure.
Each member's power is estimated as level × 42 plus gear score × 6.5, then multiplied by a clan coordination factor that scales gently with roster size. The tool sums every member from your averages, so total power = per-member power × member count × coordination bonus.
Roughly: under 250k is a fledgling coven, 250k–600k is a raiding clan, 600k–1.2M is siege-ready, and 1.2M+ is a dominant war house that can hold a keep on Blood Moon night. Thresholds drift with server age but the tiers hold across most shards.
No. A 50-member clan of level 40s in green gear usually loses to a focused 25-member clan of level 60s in epic gear. Average level and average gear score matter more than headcount once both sides can field a full siege party of 20.
Use the clan-average gear score on your roster panel. If unknown, average the item level of each member's equipped weapon and armor. Common gear sits near 120, rare near 340, epic near 620 and legendary near 900 on most shards.
Larger rosters rotate defenders, stack buffs and cover multiple lanes, so the tool applies a small coordination multiplier that grows with member count but tapers past 40 members to reflect diminishing returns from overcrowding one keep.
No. Every calculation runs in your browser in plain JavaScript. Nothing is uploaded, stored or shared, so you can safely model rival clans from public roster numbers.
Gear score gives the steepest return per point, so a clan-wide push to craft or drop rare-or-better weapons usually lifts a tier faster than grinding levels. Levelling helps most when your average is under 50; above that, gear and coordination dominate.
The power model is faction-neutral because both races reach comparable stat ceilings. Faction matters in how you spend that power: vampires favour burst siege pushes, werewolves favour sustained night defence. The score tells you the ceiling, not the tactics.
Averages hide spread. A clan averaging level 50 could be all-50 or a mix of 30s and 70s. For war, the effective roster is your best 20, so if your top 20 average higher than the whole clan, enter those numbers to model your real siege party.
Yes. Run your numbers, note the total power, then re-run with the rival's public roster size and estimated averages. The tier gap tells you whether to attack, defend or recruit before the next siege window.
