Fighting Players:
Fighting Players triggers an In Combat status for both players. If the defending player has 2,500,000 or more Bounty/Honor, the warning changes to "In Combat - Bounty/Honor at Risk", meaning they will lose Bounty or Honor if they die before combat ends. The attacking player also receives an In Combat status but can still reset their character as long as they have not taken damage from the victim or any other player. Leaving the game while either combat warning is active, known as combat logging, results in an additional Bounty or Honor penalty, and the attacker is notified that the player left the game and was penalized.

Example of the attacker's message when the victim leaves the game when the "In Combat - Bounty/Honor at Risk" warning is on their screen.

Killing Players:
Defeating another player grants Bounty or Honor, with the amount depending on both players' level and current Bounty/Honor. If the defeated player is at a similar level or up to 300 to 400 levels lower, the killer also recovers about 20 to 30% of their Health and Energy. Once a player reaches the 3/3 Bounty limit against the same opponent, that opponent is no longer considered At Risk, allowing the killer to reset after a few seconds instead of waiting for the normal combat timer to expire. Players who die receive temporary PvP protection, lasting 15 minutes in the First Sea and 10 minutes in the Second Sea, displayed as "PvP Disabled - Died Recently", and it can be disabled manually at any time. If the level difference between both players is too large, no Bounty or Honor is awarded, and the game displays "No reward, Level difference is too high!".

Action/Attack-Cancel System:
Action/Attack Cancel is a PvP mechanic where taking damage at the moment an attack is performed causes the animation to play without executing the skill, leaving the player vulnerable. This acts as a punishment for poorly timed attacks but can also occur because of lag or high ping, causing skills to cancel even if the hit appears to land after the attack was used. Although later updates reduced these issues, attack cancels can still happen and may affect players with unstable connections more frequently.

Instinct Breaking:
Instinct Breaking determines whether an attack can disable an opponent's Instinct. While some attacks break Instinct in one or a few hits, others only do so at the correct range, angle, or when the hitbox connects properly. Attacks that only graze a limb or hit from the wrong position may fail to break Instinct even if they deal damage. Instinct is also automatically broken if a player is hit while performing or holding a move.

Hitbox Delay:
Hitbox Delay is a PvP mechanic where a player's hitbox briefly lags behind their character during certain animations, especially teleport and movement abilities. If an opponent lands a hard stun before the hitbox catches up, the player can be pulled back to their original position, causing escape attempts to fail and leaving them open to combos. This effect is more noticeable with high ping or lag, making teleport-based evasive tactics less reliable in unstable connections.

Instinct Trick:
Instinct Trick, also known as Ken Trick, is an advanced PvP technique that uses Instinct to escape combos, reduce damage from certain attacks, and slightly shorten ragdoll recovery. It is one of the most important defensive mechanics in PvP and can create opportunities to counterattack if used correctly.

There are two types of Instinct Trick. The first is between moves, where the player activates Instinct during the gap between an opponent's attacks to dodge the next move if it does not break Instinct. The difficulty depends on the opponent's combo, reaction time, the player's ping, and the attacks being used. If Instinct cannot be activated because it was recently broken, escaping with Flash Step or another mobility option is usually the best alternative.

The second type is during moves, which requires activating Instinct with precise timing while an attack is already in progress. This method is much harder but can avoid attacks that normally would not break Instinct, often consuming only one or two Instinct dodges thanks to the brief invincibility frames gained during the dodge animation. Some players chain Instinct breaking attacks specifically to prevent this technique, making it important to recognize an opponent's loadout and attack patterns. A successful Instinct Trick can also leave the defender free to respond before the opponent recovers, allowing them to immediately start their own combo with an Instinct breaking attack.

Pseudo-Hitbox:
Pseudo-Hitbox refers to the difference between an attack's visual effect and its actual effective hitbox. Some attacks have a smaller hitbox than their animations suggest, while others appear to travel much farther than the distance at which they can actually deal damage. Because of this, attacks may miss even when they look like they should connect, making spacing and positioning important during PvP.

Stuns:
Stuns temporarily restrict a player's actions during PvP and are divided into three levels based on how much control they remove. Soft stuns briefly interrupt the player or disable a single type of action, such as movement, skills, or abilities like Flash Step. Medium stuns restrict two types of actions at once and are the most common form of stun. Hard stuns completely prevent movement, attacks, skills, and abilities, leaving the player unable to react until the effect ends. The stronger the stun, the easier it is for opponents to extend combos or prevent escape.

End-lag:
End-lag is a recovery period after using certain attacks during which players cannot dash, jump repeatedly, or use other moves for a short time. This mechanic limits move spamming and help balance combat by creating openings for opponents to punish poorly timed attacks. Moves with longer end-lag are harder to use safely in combos and often require careful timing or are best used as combo finishers.

Bounty and Honor:
Bounty and Honor increase a player's strength in PvP by providing damage and defense bonuses as they reach higher amounts. These buffs can significantly affect combat, making high Bounty or Honor players much harder to defeat and causing combos that work on lower-ranked players to become ineffective against players with much higher totals.

At 10,000,000 Bounty/Honor, players unlock an item that can summon a Sea Beast during PvP. These summoned Sea Beasts have less health than normal Sea Beasts and can attack other players who are not the summoner or their allies. If a summoned Sea Beast defeats a player without the summoner directly contributing damage or the victim being At Risk, no Bounty or Honor is gained or lost.

The game also includes a "No Reward, Suspicious Kill" system to prevent exploit abuse. This message usually appears when a player defeats another using only M1 attacks without taking any damage in return, causing no Bounty or Honor to be awarded. Although intended to detect cheating, it can also occur in legitimate PvP situations, particularly when using Buddha, making weapon or fighting style skills a more reliable way to secure Bounty rewards.
