Magician

INT impact to your damage range can be calculated as

Mastery comes from Spell Mastery, which is tied to the level of the spell you’re using

INT shows up in both Magic and the multiplier after it, so each point of INT is worth more the more INT you have.

LUK isn’t in the damage formula, so it has no direct impact on your damage. It contributes indirectly by letting you equip weapons with higher Magic Atk, which adds straight into Magic. Put in only enough LUK to equip the weapon you’re aiming for, and everything else into INT.

In Old School MapleStory, INT and Magic Atk traded roughly 1:1, so LUK-less was the obvious choice. In Classic World it's about 2 INT : 1 Magic Atk, so a stronger weapon can outweigh the INT you give up for its LUK requirement.

At level 50, a LUK-less Mage (the starting 4 LUK) can't equip the Cromi and uses the Hardwood Wand (34 Magic Atk) instead. A low-LUK Mage invests 36 LUK to reach the Cromi's 40 LUK requirement and gets 83 Magic Atk, 49 more. Comparing level 30 Holy Arrow:

Despite 36 less INT, the low-LUK build does about 7.2% more damage, with a higher min and max. This ignores scrolls, higher level gear and LUK / INT gear tradeoffs, which can shift the gap.

The goal isn't to invest in LUK for its own sake: put in just enough to equip a stronger weapon like the Cromi, and everything else into INT.

Magicians don’t have a weapon mastery skill. Instead, every attacking spell has its own Mastery level, listed in its skill levels as “Mastery level N”. It goes from 1 to 10 as the spell levels up and reaches 10 when the spell is maxed.

Mastery only appears in MIN damage, so a higher Spell Mastery level raises your minimum damage and tightens your damage range without changing your MAX. This makes your hits more consistent, which matters for guaranteeing hit count breakpoints. It’s also why spells like Energy Bolt are maxed early.

Each spell’s Mastery is separate. Leveling one spell doesn’t raise the Mastery of another, so a spell with only a few points in it will have a wide damage range.

Accuracy decides whether your attacks hit. It's one stat used for both physical and magic attacks.

Accuracy from your stats can be calculated as

Every stat here is your total, including equipment and buffs

Each attack compares your Accuracy against the monster's Avoid. Monsters that are a higher level than you need a lot more Accuracy to hit reliably, while being a higher level than the monster gives no extra bonus. Level is part of the formula too, so your Accuracy goes up a little every level even without adding stats.

Energy Bolt is generally recommended for first job. It costs 4 less MP per cast than Magic Claw, has 50 more range, and performs well on the flat training maps commonly used between levels 10 and 30.

Magic Claw’s main advantage is that it can attack through walls. It also hits twice, but its higher MP cost usually makes Energy Bolt more efficient for regular training.

Magic Claw’s extra hit does not automatically make it more efficient. It costs more MP and has less range than Energy Bolt. Energy Bolt is usually better for sustained training, while Magic Claw can be useful when you need to attack enemies through walls.

Yes. Every attacking spell has a separate Mastery level. Improving one spell’s Mastery does not improve the Mastery of another spell.

Mastery primarily increases minimum damage. It does not increase maximum damage, but it narrows the damage range and makes your attacks more reliable.

No. LUK-less is not mandatory. Low-LUK builds can deal competitive or higher damage by reaching weapon breakpoints that provide additional Magic Attack.

The best choice depends on the weapon progression, equipment available, and whether your gear provides additional LUK or INT.

Usually, no. Magic Guard converts incoming damage into MP damage, and MP is more expensive to restore than HP. During normal training, it is generally more efficient to avoid damage or use HP potions.

Magic Guard is most useful when taking damage is unavoidable or when surviving a hit is more important than potion efficiency.

Magic Armor is generally more efficient during first job because it provides defense without increasing potion costs. Max MP Increase can become more valuable later as your maximum MP scales upward.

Your choice depends on whether you prioritize early-game efficiency or long-term scaling. Magic Guard can also be left at a low level unless you regularly need it for dangerous content.
