Armor Crash (CoT2) - MapleStory Classic World Crusader 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. Armor Crash 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

Reduces the Physical Defense of multiple nearby monsters to 0 for a certain duration.

Needs first:

The client’s. Every figure. The box is this skill’s own lt and rb corners on that rank’s level row - the two points the client hit-tests between, measured from the origin that sits between your feet - and a rule is the same row’s range. So is which way a box faces: one that never crosses the origin is stored on one side and mirrored to whichever way you are facing, so it is drawn ahead of you; one that runs from -200 to +200 is drawn around you, because that is where it is.

Ours. The scale, which is picked so both ranks and the character fit and is stated under the drawing with a rule to read it against. The sky and the ground, which are drawn here and are not a map - the line between them is the origin, not a platform. And the character: a recorded drawing rather than the client’s own art, standing in for the class, because every item asset in the export is an inventory icon and a dressed character cannot be built out of those. See public/recorded/figures/README.md.

It is drawn at the same scale as the boxes and at no other, which is the whole point of it being there: “220 × 50 px” is not a size anybody can picture and a character standing in it is.

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

Armor Crash has no damage roll of its own.

Nothing on its level rows is a damage or healing figure, so there is nothing to break down. What it changes is elsewhere on this page - and a buff with no roll is not a gap in the data, it is the answer.

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

Armor Crash 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 Crusader 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.
