Assumptions & limitations
Shows the highest sustained single-target DPS gear from the exact engine, with the buffs above applied. It does not model:
  • Attack reach / valid styles - some bosses can't be hit by every style (Zulrah & Kree'arra need halberds for melee), so a listed style may not be usable.
  • Rare bolt/proc reductions - most per-monster caps & reductions ARE modelled (Corp halving, Zulrah's 50 cap, Kraken's 1/7 to non-magic, Ice demon, Duke), but an enchanted-bolt proc against a reducing monster can be slightly overstated. Never the recommended style anyway.
  • Boss phases - multi-phase bosses (Zulrah, Vorkath, Alchemical Hydra) are scored one form at a time.
  • Special attacks, prayer-switching, AoE, or survivability - no spec cycles (DWH/BGS), no protection prayers, no multi-target (chins).
  • Pure DPS, not practicality - reports the literal highest damage-per-second, so a fast-but-impractical weapon (e.g. Karil's crossbow, which degrades to dust) can top the raw numbers.
Salve and Dragon/demon-bane bonuses auto-apply from the target's type; the other buffs are the toggles above.
