Effect

Defines buff and debuff effects with their properties, durations, and stat modifiers

Defines all buff and debuff effects in the game, including potions, scrolls, seals, skill effects, and debuffs. Each effect specifies its index, group, duration behavior, persistence, and associated stat values.

Configuration Structure

Effect Element

Each <Effect> element defines a single buff or debuff effect.

Attribute	Type	Description
Index	int	Unique effect identifier (1-204). Referenced by skills, items, and game mechanics.
Group	int	Effect group number. Only one effect per group can be active at a time. Same group effects replace each other.
ItemIndex	int/*	Item that grants this effect (e.g., 6699 for Seal of Ascension). Use * if not item-based.
Name	string	Display name of the effect (for reference only, not shown to client).
Save	0/1	Whether effect persists after logout. 1 = save to database, 0 = clear on disconnect.
Type	int	Effect timing mode. 0 = regular countdown (counts down in seconds, can be cleansed), 1 = special countdown (counts down in seconds, cannot be cleansed), 2 = persistent countdown (counts down in seconds, cannot be cleansed, saves as Unix timestamp).
Flag	0/1	Debuff flag. 0 = buff (beneficial), 1 = debuff (removable by cleanse effects).
Count	int/*	Effect duration in seconds. For Type 0/1: counts down each second. For Type 2: added to current Unix time to calculate expiration timestamp. Use * for skill-provided duration.
Value1	int/*	Effect-specific value 1. Meaning varies by effect (damage bonus, stat modifier, etc.). Use * for skill-provided value.
Value2	int/*	Effect-specific value 2. Often used for secondary bonuses or timing parameters. Use * if unused.
Value3	int/*	Effect-specific value 3. Used by complex effects with multiple parameters. Use * if unused.
Value4	int/*	Effect-specific value 4. Used by complex effects with multiple parameters. Use * if unused.

Important Behavior

Group-Based Replacement: When a new effect is added with the same Group as an existing effect, the old effect is removed and replaced. This prevents stacking multiple buffs of the same category.

Value Inheritance: When an attribute is set to * (asterisk), the value is provided at runtime by the skill or item that applies the effect. When set to a number, that value is always used regardless of the source.

Type Differences:

• Type 0: Countdown in seconds. Can be removed by cleanse skills. Best for temporary combat buffs/debuffs.

• Type 1: Countdown in seconds. Cannot be cleansed. Used for event states and special effects.

• Type 2: Countdown in seconds with absolute expiration time. Cannot be cleansed. Internally stores both:

  • m_time = Unix timestamp when effect expires (time(0) + Count)

  • m_count = seconds remaining (decrements each second)

  • When saved to database, stores m_time so expiration time is preserved across server restarts.

  • When loaded from database, recalculates m_count = m_time - time(0).

Save Flag Impact: Effects with Save="0" are cleared when players log out. This includes most debuffs and temporary PvP effects. Effects with Save="1" persist in the database and are restored on login. For Type 2 effects with Save="1", the exact expiration timestamp is preserved, so effects will expire at the correct time even if the player logs out and back in.

Effect Value Meanings

The Value1-4 attributes have different meanings depending on the effect:

• Damage/Defense Buffs: Value1 = amount to add (e.g., +30 damage)

• Percentage Buffs: Value1 = percentage boost (e.g., 50 = +50% experience)

• Stat Elixirs: Value1 = stat points to add temporarily

• DoT (Poison) Effects:

  • Value1 = attacker object index (who applied the effect)

  • Value2 = tick interval in seconds (damage applied every N seconds)

  • Value3 = damage percentage of victim's current HP (e.g., 5 = 5% of current HP per tick)

  • Value4 = damage cap (max damage per tick, 0 = no cap)

• Multi-Stat Buffs: Value1 = primary stat, Value2 = secondary stat, etc.

Examples

Item-Based Buff

<!-- Seal of Ascension - +50% Experience for 30 minutes -->
<Effect Index="29" Group="60" ItemIndex="6699" Name="Seal of Ascension"
        Save="1" Type="2" Flag="0" Count="1800"
        Value1="50" Value2="*" Value3="*" Value4="*"/>

Breakdown:

• Type="2" with Count="1800" = duration of 1800 seconds (30 minutes). Server calculates expiration as time(0) + 1800.

• Save="1" = persists through logout (expiration timestamp saved to database)

• Value1="50" = +50% experience rate

• Value2-4="*" = unused for this effect

Skill-Based Debuff

Multi-Value Buff

Stat Elixir

Common Issues

Effect Not Persisting: Check that Save="1" is set for effects that should survive logout. DataServer must also be configured to save effects.

Effects Stacking Incorrectly: Verify the Group attribute. Effects in the same group replace each other instead of stacking.

Type 2 Effects Not Expiring: Ensure Count value is in seconds. Common mistake is using minutes (multiply by 60) or forgetting that Type 2 adds to Unix timestamp.

Index Range: Effect indices range from 1-204 (based on server version). The server supports up to 256 total effects (MAX_EFFECT), but only indices with corresponding configuration entries will work.
