[h3]About the Buff Skill Spring, Summer, Autumn, Winter[/h3]


While Sei Shonagon’s primary attribute is Poison, she can add four different attributes through her four buff skills Spring, Summer, Autumn, Winter.

Skill Spring Dawn adds Wind attribute at 25% of skill power,
Skill Summer Night adds Thunder attribute at 25% of skill power,
Skill Autumn Dusk adds Water attribute at 25% of skill power,
Skill Winter Daybreak adds Holy attribute at 25% of skill power.
Additionally, each one multiplies damage by 1.25.

Up to four buff effects can be active at the same time.
The effect duration is 30 seconds when in Vanguard Swap, and 20 seconds when accompanying.

----------------------------------------------------------------

■ About Attribute Addition
When under the buff effect of Spring Dawn, Wind attribute is added at a value equal to 25% of the used skill’s power.

Image example (with skill distribution shown as 100)


----------------------------------------------------------------

■ About Damage Multiplication
Spring, Summer, Autumn, Winter increases damage by 1.25x per buff effect, and when all buffs are active, damage is doubled.
During this, the damage cap is ignored.
*When applied to player characters, damage multiplication does not apply to monsters with the Covenant trait.

----------------------------------------------------------------

■ Other Effects
Additionally, the buffs from Spring, Summer, Autumn, Winter have the following effects:
・Corresponding Attribute +50
・Reduce the cooldown of the [Ougi Thorn Season Distant Yet Near] by 10 seconds
・Attack -10%
・Inflicts Poison status that deals 100 damage per second ・Inflict Poison status for 20 seconds, dealing 150 damage per second

Sei Shonagon constantly activates the buff Toxic Reversal, which converts poison damage into healing, allowing her to recover from poison damage.

----------------------------------------------------------------

■ Applying Buffs to Others
Spring, Summer, Autumn, Winter, when activated, forcibly grants the buff to party members. Along with the buffs, the drawbacks of Poison status and Attack -10% are also applied, up to all four at once.

Depending on the monster, the drawback may reduce the damage dealt.
Spring, Summer, Autumn, Winter is a powerful buff, but be mindful that it also forcibly applies drawbacks!

Additionally, even when accompanying you, Sei Shonagon may apply the Spring, Summer, Autumn, Winter buff to player characters.

*Spring, Summer, Autumn, Winter is only applied to player characters in the party and is not applied to Vanguard Characters or Battle Mounts.
*The poison damage from Spring, Summer, Autumn, Winter will not reduce HP to 0; a minimum of 1 HP will be maintained.
