OSRS Combat Calc

OSRS Splashing Calc

Splashing trains Magic slowly but almost without attention: every cast misses, so you earn only the spell’s base XP. Pick the spell you will autocast to see casts, runes, cost and how many 20-minute check-ins your goal takes.

Calculate your result

Adjust the fields to calculate your result.

Model limits: Splashing needs a total magic attack bonus of -64 or lower so every cast misses. Only base spell XP is earned; no Hitpoints XP. After 20 minutes without input you stop attacking until you interact again. Rune counts are raw, before staves save them.

How OSRS Splashing Calc Works

  1. Enter your current Magic level and, if you know it, your exact Magic XP.
  2. Enter your target Magic level.
  3. Pick the spell you will autocast, from Wind Strike to Fire Surge.
  4. Keep 1,200 casts per hour for 1 cast every 5 ticks, or enter your own rate.
  5. Enter your rune cost per cast and read the result.

OSRS Splashing Calc Formula

The OSRS Splashing Calc formula is Casts = ⌈Magic XP remaining ÷ base spell XP⌉, with no damage XP.

Casts = ⌈Magic XP remaining ÷ base spell XP⌉
Hours = casts ÷ casts per hour
Check-ins = ⌈hours × 3⌉, 1 every 20 minutes

  • 1 cast every 5 ticks (3 seconds) gives 1,200 casts per hour.
  • Fire Strike gives 11.5 XP per cast, or 13,800 XP per hour.
  • Splashing gives 0 Hitpoints XP.
