В Lineage 2 buff Mental Shield (Mental Shield) reduces the chance of negative effects being applied to the character Sleep, Hold, Fear, Silence, and also mental debuffs. What are mental debuffs we will analyze in this article, as well as formulas for calculating debuffs using a buff Mental Shield and without it.

Mental Shield Buff – A Complete Breakdown

Healthy!
Mental Shield is one of the key buffs in Lineage 2, directly impacting survivability in PvP by reducing the chance of being affected by effects like Sleep, Fear, Silence, and other mental debuffs. In practice, this means that without it, a character becomes vulnerable to crowd control, while with it, they can significantly more easily ignore dangerous spells and stay in combat. However, it's important to keep in mind that the formulas, balance, and strength of debuffs may differ across different projects, so it's important to familiarize yourself with the current version before playing.

Mental Shield lvl 4 - Increases resistance to hold/sleep/mental attacks by 50 units for 20 minutes.

В Lineage 2 mental attacks (Mental Attacks) – these are spells and skills that impose control effects that hinder the enemy’s actions. They are subject to the influence of Mental Shield and mental resistance (parameter MEN).

Here is a list of some mental attacks: Arcane Chaos, Aura Flash, Curse of Doom, Forget, Horror, Lure, Fear, Mass Fear, Peace, Requiem, Seal of Mirage, Seal of Silence, Shield Slam, Silence, Song of Silence, Switch, Trick, Sword Symphony, Veil, Erase, Stun, Hammer Crush, Stun Shot, Thunder Storm, Paralyze, Bluff.

How does the Mental Shield buff protect against these attacks?

In the game code, mental debuffs have a base chance to pass, which can vary depending on the skill.

Each character has resistance to mental attacks. (Mental Resistance), depending on equipment, racial characteristics and buffs.

В Lineage 2 The chance of applying mental debuffs is calculated using the following formula:

P_final = P_base * (1 - (R - P) / 100)

Where:

• P_final – the final chance of applying a debuff.
• P_base – the basic chance of passing the debuff (for example, Fear this is 80%).
• R(resist) - the target's resistance to mental attacks (includes MEN and buffs like Mental Shield).
• P(power) – the power of the debuff, some debuffs have a Power value.

Example of calculation with buff Mental Shield (+50 resistance):

• P_base (Fear) = 80%
• R(resist)= 50 (Mental Shield gives +50 mental protection), MEN and other target resistances = 0 (for simplicity).
• P(power) = 0 (Fear does not have Power).

P_final= 80 * (1 - (50-0)/100)

P_final = 80 * (1 - 0.5)

P_final= 80 * 0.5 = 40%

Bottom line: Chance of passing Fear decreases with 80% to 40%.

If the target has additional resistances?

Let's say the target has 20 additional resistance from MEN, then:

P_final= 80 * (1 - ((50+20)-0)/100)

P_final = 80 * (1 - 0.7)

P_final= 80 * 0.3 = 24%

Bottom line: If the target has a buff Mental Shield (+50 units), and also +20 units from MEN, then the chance of passing Fear decreases to 24%.

Some spells can ignore part of the resistance to mental attacks (for example, Raid bosses or opponents with very high magical attack, parameter INT affects the chance of passing debuffs). You can see all the parameters of the characters and how to change them in our article about paints and tattoos here.

Conclusion: buff Mental Shield works as a resistance increase, reducing the likelihood of mental debuffs being applied, but not making the character completely immune. In a real fight, the chance still depends on the parameters of the attacking and defensive characters. In the case of the attacker, the chance of passing debuffs strongly depends on the parameter INT, and in the case of a defensive character, the parameter plays an important role MEN and resists.
