Trait Fruits—How to Change IVs

When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.

+Spd and -Def

G!Olwen's best IVs are +Spd and -Def. With a +Spd IV and Swift Sparrow 2, Olwen will have a pretty easy time getting a lot of follow-up attacks. Her Def is already her poorest attack, so it is the go-to for a dump stat.

+Spd for a +10 Merge

If you are building a +10 merged G!Olwen, we recommend a +Spd IV. With +10 merges and a Spd boon, her Spd will reach 42, and she will excel at gaining follow-up attacks. If you want to buff her Spd through ally support skills instead, +Atk is a good option as well.

Green Tome Olwen Best Weapon Refine

Effect of Olwen's Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
Thunderhead	SP: 400
Might: 14　Range: 2　HP: Grants bonus to unit’s Atk = total bonuses on unit during combat. If an ally initiates combat against a foe within 2 spaces of unit, inflicts Spd/Res-5 on that foe during combat. ：500　：200

We recommend the Special Effect Refine for Thunderhead

Upgrading Thunderhead with the special effect upgrade will inflict Spd/Res-5 on foes near Olwen when an ally initiates combat against them. This will greatly weaken them for Olwen, allowing her to swoop in for an easy follow-up attack, which will effectively deal 10 extra damage. This skill works very well if you intend to use Olwen along with some other support attackers.

Green Tome Olwen Roles, Strengths, and Weaknesses

Green Tome Olwen Roles

Olwen - Righteous Knight Roles
Close-Physical	Ranged-Physical	Close-Magic	Ranged-Magic
Physical Wall	Magic Wall	Effective Weapon	Movement Assist
Exclusive Skill	All-Range Counter	Recovery	Refresher
Legendary	Mythic	Duo / Harmonized	Resplendent

G!Olwen is a ranged magic attacker (range = 2). Therefore, when not accounting for the Weapon Triangle, the amount of damage she deals will be equivalent to her Atk minus the foe's Res stat.

Green Olwen Strengths

Exclusive blade type tome

G!Olwen's exclusive weapon Thunderhead is essentially a better version of Gronnblade. Like Blade-Tomes, it will add active bonuses on Olwen to her Atk, but without the cooldown count+1 drawback. Since she is a cavalry unit, she can make use of buffs through skills like Goad Cavalry to greatly multiply her damage output.

Offensive stats increase in player phase

With the A skill Swift Sparrow 2, Olwen gains Atk/Spd+4 when she initiates combat. This will make it easier for her to gain follow-up attacks, and allow her to deal even more damage, making it very versatile and easy to use.

Green Olwen Weaknesses

Weak to Cavalry Effective Weapons

G!Olwen takes 1.5x damage from cavalry-effective weapons like Ridersbane, and one blow from this type of weapon is sure to take her down. Make sure you know what weapons you are up against before hopping too far into the line of battle!

Heroes with Effective Skills

Struggles against physical attacks

Since G!Olwen has a pretty poor Def stat, she will take a lot of damage from physical attacks. If she takes an attack from a Brave weapon, the likelihood of her surviving is rather slim, so steer clear of this type of enemy.

Value of Skills	★★★★☆

Inheriting Swift Sparrow 2

G!Olwen can be foddered off to teach the very useful skill Swift Sparrow 2 to another unit. However, as a pretty strong mobile ranged unit, we recommend building and merging any duplicates instead of foddering them off.
