Notes

• Between each skill configuration there is a #===... separator.
• This file never uses spaces, only tabs.
• If you specify a wrong zts value (translation), it will display that zts value (for example zts3e) in game.
• One skill can have more than one zts description line.

warning

It's important to remember that values are separated by tabs, not spaces.

Visual Studio Code replaces tabs with spaces by default. That's why it's recommended to use Notepad++ or other text editor that will not replace tabs with spaces.

NAME and Z_DESC

• {SkillCodeName} and {DescriptionCodeName} contain the key for translation. For example zts3e is a key for translation.
• Translations can be found in _code_<lang>_<filetype>.txt files (for example _code_en_Skill.txt).
• If you specify a wrong zts value (translation), it will display that zts value (for example zts3e) in game.

BASIC

	BASIC	{Index}	{BCardVNUM}	{BCardSub}	{EffectVal_1}	{EffectVal_2}	{Target}

See definition in Item.dat.

The only difference is {Target} which is a bit different:

Value	Description
0	Self - BCards with this will be added to caster's stats before the attack so that they work during the attack. And then removed after. All normal stuff like "Melee damage increased by x" or "Crit damage incr. by x%"
1	I think it is bonuses that also add before the attack and other calculations (so if a debuff is inflicted with this 1, the attack have to take this debuff to calculations)
2	No idea, but it targets the caster, like 0 and 1
3	All Targets - basically this BCard triggers on all targets after the attack
4	No idea, but about 90% of "Decreases target's HP by x%" have it, alongside with a bunch of other normal enemy-related BCards, like "x% chance to inflict x debuff"

The Opennos parser processes BCards with the following logic:

• If BCardVNUM is 0 or 255, the BCard is skipped
• SubType is calculated as: ((BCardSub + 1) * 10 + 1 + (EffectVal_1 < 0 ? 1 : 0))
• IsLevelScaled is true if EffectVal_1 >= 0 and EffectVal_1 % 4 != 0
• IsLevelDivided is true if EffectVal_1 >= 0 and EffectVal_1 % 4 == 2
• FirstData is EffectVal_1 if positive, otherwise -EffectVal_1 / 4
• SecondData is EffectVal_2 / 4 if positive, otherwise -EffectVal_2 / 4
• ThirdData is Target / 4 if positive, otherwise -Target / 4

FCOMBO

	FCOMBO	{IsCombo}	{FirstActivationHit}	{FirstComboAttackAnimation}	{FirstComboEffect}	{SecondActivationHit}	{SecondComboAttackAnimation}	{SecondComboEffect}	{ThirdActivationHit}	{ThirdComboAttackAnimation}	{ThirdComboEffect}	{FourthActivationHit}	{FourthComboAttackAnimation}	{FourthComboEffect}	{FifthActivationHit}	{FifthComboAttackAnimation}	{FifthComboEffect}

IsCombo

If true, enables the "animation combos". Each consecutive attack deals more damage.

Combo Slots

There are 5 "slots" for the fcombos:

• 1st one deals 100% damage
• 2nd - 105% damage
• 3rd - 115% damage
• 4th and 5th are unknown because never used on official

The damage bonus is added to base attack damage (e.g. melee).

Each slot contains:

• {___ActivationHit} - number of consecutive hits that triggers this animation
• {___ComboAttackAnimation} - animation ID
• {___ComboEffect} - animation VFX

CELL

	CELL	{unk1}	{unk2}	[{xOffset}	{yOffset}	{isOn}]x20	{Reverse}

20 times [{xOffset} {yOffset} {isOn}], it's like a list of points (cells) for Special Area skills. The offsets are relative to your character or the target (depends on {Reverse}). If you need more info about it - you will have to figure it out yourself.

unk1, unk2

Unknown field. Purpose not documented.

xOffset yOffset isOn (20 instances)

There are 20 instances of this field.

• xOffset - X coordinate offset for each cell position.
• yOffset - Y coordinate offset for each cell position.
• isOn - Boolean value indicating if this cell position is active.

Reverse

Boolean value determining if offsets are relative to the character (false) or target (true).

Common Issues

Game Crashes

Make sure format is correct:

• Are you using tabs instead of spaces?
• Is there a #===... separator between each skill configuration?
• Are the values in the correct order?
• Are the values in correct range?
• Do you have the correct amount of parameters in each line?

How to Change Skill Icon?

SkillIconImg is located in EFFECT row. You need to change it to the correct icon id. If icon does not exist it will default to question mark icon.

New icons can be added to the NSipData.NOS file. The file name is the icon id.
