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.

+Res / -Def

The best IVs for Bastian are +Res and -Def. His Res is among the highest in the game and it heavily impacts his main role of being a Magic tank.

His Def is abysmal and is a safe bane to take as it will not impact any of his matchups.

+Res for a +10 merge

We recommend +Res when merging Bastian up to +10 in order to maximize his survival, which is essential for any defensive unit.

Bastian Roles, Strengths, and Weaknesses

Bastian Roles

Bastian - Crimea's Keystone 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

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

Bastian Strengths

Gronndeer+ is a good inheritable tome

Bastian debuts a new line of inheritable tomes in Gronndeer+. This deer series tome grants Atk+5 to unit and inflicts Atk-5 and a Guard effect onto the foe.

Both the Spendthrift effect and the Guard effect help offensively and defensively, ensuring that Bastian survives combat.

Bastian Weaknesses

Lack of Unique Skills

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

Green Tome infantry units are quite abundant in the game, and lacking an exclusive weapon makes Bastian replaceable by better units.
