What is Morph?

In the game NosTale, a "Morph" (from the word morphing, meaning transformation) is a process in which the player's character dynamically changes form upon equipping and activating a Specialist Card.

From a technical perspective, a Morph is represented by a unique numerical value (known as a Morph ID), which is calculated by the server and differs from the ID of the item itself located in the inventory. When a player activates a card, the server transmits this new value in network packets to the game client.

As a result, the game engine receives an instruction to replace the hero's standard appearance. This change involves loading a new character sprite and updating the portrait icon visible in the top-left corner of the interface. Along with this visual transformation, the character also gains powerful stat boosts and an entirely new set of combat skills assigned to that specific class.

Morph	Description
$morph 0	By default you are using Morph 0. That will load sprite based on you class
$morph 20	When you equip a Specialist Card your Morph is changed
$morph 1001	That can be used to change your appearance to Monsters too.

How to change Morph?

OpenNos command

In OpenNos based servers you can change Morph by using the $morph <morph_id> command.

Packetlogger packet

You can also send to yourself c_mode packet.

Packetlogger packet (pattern)

c_mode 1 <character_id> <morph_id> 0 0 0 100 0

Packetlogger packet (example - change your character to Pirate)

c_mode 1 42067 16 0 0 0 100 0

How Icon IDs work

Icon IDs for the portrait (top-left corner) are derived from item VisualChangeId and class. The 6th value in the item's INDEX row in Item.dat is the VisualChangeId value used in these formulas. (See Item.dat for more information.)

Specialist Card (SP) icon — character

• Male: 32500 + (VisualChangeId - 1) * 2
• Female: 32500 + (VisualChangeId - 1) * 2 + 1

Example

Pirate Specialist Card (Vnum: 4099)

Item.dat

	VNUM	4099	0
...
	INDEX	4	4	0	12	915	16
...

6th value in INDEX is VisualChangeId = 16. Icon IDs: male = 32528, female = 32529.

Class icon (no SP equipped)

• Male: 32000 + classId * 40
• Female: 32000 + classId * 40 + 20

classId	Class Name	Male Icon	Female Icon
0	Adventurer
1	Swordsman
2	Archer
3	Mage
4	Martial Artist

Partner Specialist Card icon

Formula (Partner Specialist Card icon)

25000 + VisualChangeId

Monster icon

Monster icon is calculated differently. See monster.dat (iconId section).

Code snippets

function getClassIconId(classId: number, gender: "male" | "female") {
  return 32000 + classId * 40 + (gender === "female" ? 20 : 0);
}

function getSpIconId(item: Item, gender: "male" | "female") {
  return (item.design - 1) * 2 + 32500 + (gender === "female" ? 1 : 0);
}

function getPartnerSpIconId(item: Item) {
  return item.design + 25000;
}
