One build, focused answers

Each calculator answers one decision you face in-game.

Training: Best mob for your current build
Combat: Weapon and one-hit requirements
Progress: XP, time, potion, and skull costs

Saved presets stay on your device.

Answers for the next move.

Enter the stats a question needs, then get a result you can use in your next session.

Choose the right target: Compare your level, skill, weapon, and buff to find a practical training mob.
Check damage first: Estimate one-hit thresholds and see which weapon fits your target and attack type.
Plan time and gold: Work out XP goals, grind time, potion costs, PK skull costs, and offline training.
