What Is Maximum Magic Hit

Maximum Magic Hit is the highest damage a single Magic spell can deal in Old School RuneScape. It shows the most damage you can do with one cast of a spell when you have the right equipment and boosts. This number helps players plan their gear setup and choose the best spells for different situations.

How Maximum Magic Hit Is Calculated

Formula

The formula multiplies your spell's base damage by a percentage based on your equipment bonus. For example, a spell with 20 base damage and 15% magic damage bonus becomes 23 damage. The game always rounds down, so any decimal is dropped. This means small bonuses might not always increase your max hit until they cross certain thresholds.

Why Maximum Magic Hit Matters

Knowing your maximum magic hit helps you pick the right spell and gear for different monsters. Higher max hits mean faster kills and more damage per cast. This saves money on runes and time during training or boss fights.

Why Maximum Hit Is Important for Slayer Tasks

When doing Slayer tasks, you want to kill monsters as fast as possible. A higher max hit means each spell does more damage on average. This helps you finish tasks quicker and earn more Slayer points per hour. Players often check their max hit before expensive purchases to make sure the upgrade is worth it.

For Bossing and High-Level Content

Bosses have lots of hitpoints, so every point of damage counts. Players aiming for efficient boss trips need to know their exact max hit. This helps calculate how many casts are needed to kill a boss and plan inventory space for runes and food. The difference between a 30 and 35 max hit adds up over thousands of casts.

Maximum Magic Hit vs Magic Accuracy

Maximum hit and accuracy are two different things. Your max hit tells you the most damage you can do when a spell lands. Accuracy tells you how often your spells actually hit the target. A setup with high damage but low accuracy might do less total damage than a balanced setup. Players need to consider both when choosing gear.

Example Calculation

A player has 75 Magic and wants to cast Fire Wave, which has a base max hit of 20. They are wearing equipment that gives 15% magic damage bonus. They have no potion boost active, so their magic boost is 0.

The calculator takes the spell base max hit of 20 and multiplies it by 1.15, which is 1 plus 15% divided by 100. This gives 23. The floor function keeps the result as 23 since there are no decimals to drop.

Maximum Magic Hit: 23 hitpoints

This player's Fire Wave can hit up to 23 damage per cast with their current equipment. If they wanted to reach 24 damage, they would need enough extra magic damage bonus to push the calculation above 23.5, which would require about 18% total magic damage bonus.

Frequently Asked Questions

Who is this OSRS Magic Calculator for?

This calculator is for Old School RuneScape players who want to know their maximum magic damage. It helps players planning gear upgrades, training Magic efficiently, or preparing for boss fights. Players of all skill levels can use it to compare different spell and equipment combinations.

Does magic level affect max hit?

For most standard spells in OSRS, magic level does not directly affect max hit. The max hit comes from the spell itself and your equipment damage bonus. However, magic level does affect your accuracy, which determines how often your spells hit. Some special attacks and powered staves scale differently.

What equipment gives magic damage bonus?

Several items provide magic damage bonus in OSRS. These include occult necklace, tormented bracelet, ancestral robes, and various capes. The total bonus is shown in your equipment stats menu. Stack multiple pieces to reach higher damage thresholds.

Does this calculator work for powered staves?

This calculator is designed for standard spells with fixed base max hits. Powered staves like the Trident of the Seas have their own scaling formulas based on magic level. For powered staves, check the specific item's formula or use a dedicated powered staff calculator.
