Moons of Peril OSRS: Weaknesses and Gear Decisions
The three Moons reward different melee styles and defensive consistency. Free in-dungeon supplies reduce cash cost, while flat armour and healing mechanics make ordinary DPS an incomplete estimate.
Do not reuse one weapon blindly
Each Moon has a different zero-defence melee style. A compact three-weapon plan can outperform an expensive single weapon used against the wrong defence profile.
What the calculator can tell you
Use separate loadouts to compare direct attacks against Eclipse, Blue and Blood Moon. This exposes accuracy and max-hit differences caused by their stab, crush and slash defence profiles.
The raw number is not a full encounter simulator. Eclipse has flat armour, Blood can heal, and every room has mechanics that pause or redirect damage. Use calculated DPS to choose gear, not to promise an exact chest time.
Why the activity works for mid-level accounts
Neypotzli supplies food, potions and other resources between fights, reducing the cost of learning. The armour sets also form useful stepping stones, so account progression value may be higher than a live GE total suggests, especially for iron accounts.
Compare Moon loadouts
Start with Blood Moon, then switch the target to Blue and Eclipse using separate loadouts.
