Blizzard (CoT2) - MapleStory Classic World Sniper skill

Read from the Closed Online Test 2 client, pulled 12 August 2026.

CoT2: From Closed Online Test 2 (Beta 2). Not in the Public Release; kept here as a record.The Public Release has no 3rd job. Blizzard is kept from Closed Online Test 2 with every rank as the test had it, so what this page says is the test’s, not the live game’s. What the release removed

Fires an ice arrow at an enemy in front that freezes the surrounding area on impact, dealing Ice-elemental damage to up to 4 enemies. Targets hit will suffer from a Slow effect that reduces movement speed for 2 seconds. Deals increased damage to ice-weak enemies, but deals reduced damage to ice-resistant enemies and cannot slow them.

Available the moment you advance.

What ranking it up buys

One row per number that moves rank to rank: what it is at rank 1, what it is at the last rank, and the difference. The track marks every rank at its own place between the two, so a skill that does most of its work in the first few ranks looks like one - and several do.

Every figure comes off the client’s own level rows rather than out of the tooltip sentence, so a rank the client is silent about is a gap here rather than a guess.

What it rolls

A damage number whose inputs are hidden is worse than no number, so all of them are on the page. Level 70, which is this job’s own unlock level. 217 DEX, which is every base point the level allows that is not being spent meeting the weapon. 145 DEX to hold a Gross Jaeger. 92 weapon attack, and mastery 10 from this chain's own mastery skill.

No equipment beyond the weapon, no buffs, no potions and no monster on the other end: this is the roll before anything is done to it. What the game prints also depends on the level gap to what you hit and on its defence, and neither is in this figure.

Rank 30

1130-1267

175% of the roll

high = skill% x (1.0 + (DEX x mult + DEX) / 100 + att / 50) x weapon attack

low = skill% x (0.8 + (DEX x mult x mastery + DEX) / 100 + att / 50) x weapon attack

How often you swing

Every weapon carries a stage from 2 (fastest) to 8 (slowest), and the label printed beside it is not reversible: “Fast” is stage 4 or 5, so the stage is what a booster has to be applied to.

What the export does not carry is milliseconds per stage. So this says which weapon swings sooner than which, and cannot say how long either takes - which is also why damage per second is not a number this site prints anywhere.

Best rung at level 70	Bare	No booster
Gross JaegerCrossbow	Slow (7)	-

This job has no , so the weapon’s own stage is the whole story.

Weapon multipliers

The multiplier is the weapon’s, not the skill’s, and it is the largest single term in the roll.

Weapon	Swing	Stab
Crossbow	1	1

A ranged weapon carries one multiplier and one action, so there is no swing-or-stab coin flip in the numbers. Firing one at something standing next to you is the exception, and it is punished: the stat divisor goes from 100 to 300 and the attack divisor from 50 to 150.

Closed Online Test 2 to Public Release

Each diff was generated on its own date and the rest of the snapshot was synced later, so a change made between the two would not appear here. Where they disagree, the rank rows above are the newer read.

Closed Online Test 1 to Closed Online Test 2

Blizzard is new in Closed Online Test 2. It did not exist in Closed Online Test 1, so there is nothing to compare it against.

The rest of the Sniper book

How long a cast takes. The client ships a frame timing for every action, but the game scales an action by the weapon’s attack speed and the rule that does it is not in the export. So nothing here is milliseconds of real cast time, and nothing on this site prints damage per second.

How the search steps. The box says what area a cast catches, and three things about how it is searched are on no row anywhere: where the search starts, relative to your feet; the step it moves in, if it steps rather than sweeps; whether a wall or a platform edge stops it. Drawing them would mean taking somebody else’s reverse engineering of the client and presenting it as ours.

Whether it can be cast in the air, and what a monster’s defence does to the roll. No cast-position column exists, and the roll above is the number before anything on the other end is applied.

And all of it is Closed Online Test 2's: the Public Release does not have this skill.
