Oswin Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (21) HP Superboon ★★★★★
Atk (17) Attack Boon ★★★★★
Spd (5) No Spd IV ★★★☆☆
Def (10) Def Boon ★★★★★
Res (8) Res Boon ★★☆☆☆

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws

See the IV Checker for All Units 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.

+Def / -Spd

The best IVs for Oswin are +Def and -Spd. Oswin's Def is among the highest in the game at base 49, raised to 53 with a superboon. Boosting Def helps Oswin perform better as a physical tank.

Oswin's Spd and Res are his least important stats. We opted for a Spd bane in case Oswin gets attacked by dragons or other foes with adaptive damage.

+Def for a +10 merge

We recommend a +Def IV when merging Oswin up to +10 to maximize his physical bulk.

Oswin is a close physical attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage he deals will be equivalent to his Atk minus the foe's Def stat.

Oswin Strengths

Min-maxed statline

Oswin's base stats are all very high on physical traits, with base 51 HP, 47 Atk, and 49 Def. With these stats, Oswin is perfectly suited for a physical tank role, similar to the enemy Lance Knights players fight on Abyssal difficulty in PvE Hero Battles.

With enough investment, Oswin can soak multiple physical hits for his team and ensure that his foes cannot pierce through his bulk.

Campaign Lance+ creates a large stat swing

Oswin's inheritable Campaign Lance+ grants him Atk/Def+5 during combat, inflicts up to Atk/Def-10 onto his foe, and grants him 10 HP post-combat healing.

While not as exciting as Arcane or exclusive weapons, it gets the job done by granting Oswin physical stats and healing to keep him healthy throughout multiple combats.

Oswin Weaknesses

Requires heavy investment

While Oswin's base stats are all focused on key areas and are quite impressive, his base kit is lackluster.

He will require significant investment for all skill slots to become relevant in today's metagame.

Low Res

Oswin's Res is quite low at only base 27, leaving him vulnerable to magic and adaptive damage.

He will be completely reliant on his high HP stat to absorb magic damage. Ensure Oswin is away from these type of foes.

Lack of Unique Skills

Oswin suffers from not having any unique skills to call his own, making him unable to stand out amongst other units.

Lance armored units are quite abundant in the game, and lacking an exclusive weapon makes Oswin replaceable by better units.

Weak to Armor Effective Weapons

Oswin takes 1.5x damage from armor-effective weapons like Randgríðr, and one blow from this type of weapon will deal significant damage. Make sure you know what weapons you are up against before hopping too far into the line of battle!

Should You Unlock Potential for this Hero? A Rank Icon

We Recommend You Unlock Potential for Oswin - Impregnable Knight!

We recommend that you use Unlock Potential to bring Oswin - Impregnable Knight from 4 Stars to 5 Stars. Oswin - Impregnable Knight is a very useful high bulk armor, so we recommend you Unlock Potential for Oswin - Impregnable Knight if your team lacks a strong high bulk armor.
