+Spd/-Res

The best IVs for Erk are +Spd and -Res. A higher Spd stat allows Erk to get a ton of follow-up attacks on his foes. Additionally, his Spd is a superboon so you should take advantage of that as much as possible. Taking a bane in Res balances his defensive stats, that is ideal for survival so you should aim for that as much as possible! It might be tempting to maximize his Res stat by taking a Def bane, but it is already low and it is a superbane so taking it will be very bad for his survival!

+Spd for a +10 Merge

We recommend a +Spd IV when merging Erk to 10. This is for the same reasons as above. You can also take a +Atk IV if you plan on using support and buffs to supplement his Spd.

Erk Roles, Strengths, and Weaknesses

Erk Roles

Erk - Studious Mage Roles
Close-Physical	Ranged-Physical	Close-Magic	Ranged-Magic
Physical Wall	Magic Wall	Effective Weapon	Movement Assist
Exclusive Skill	All-Range Counterattack	Recovery	Refresher
Legendary	Mythic	Duo/Harmonized	Resplendent

Erk 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.

Erk Strengths

Rauðrfox+ inflicts defbuffs upon initiation

Spd/Res Solo 3 and Rauðrfox+ combines for a great stat gap betweene Erk and his foe.

Rauðrfox+ inflicts an in-combat -4 Atk/Spd/Def/Res to Hubert's foe when he initiates combat. This makes Hubert a great player phase attacker as this can be treated as a Swift Sparrow-like skill. Additionally, it is an in-combat buff which makes it easy to stack with other buffs.

Spd/Res Solo 3 grants a nifty Spd/Res boost

If Erk enters combat without an adjacent ally, he gets a +6 Spd/Res boost through his A skill. This is pretty easy to trigger and stacks with Rauðrfox+.

Spd Opening 3 grants a buff to the speediest ally

+6 Spd is granted for 1 turn to Erk's fastest ally at the start of each player phase. This is very helpful and it is enough of a buff to allow an ally to score a follow-up attack if they are tied with someone. This buff will be granted regardless of Erk's positioning in relation to that ally.

Erk Weaknesses

Lack of a Prf Weapon Makes Him a Mediocre Unit

Since Erk does not have a Prf weapon, he will have a hard time scoring high in the Arena and is easily powercrept by other mages.

If you do like Erk, however, you can perhaps give him another weapon such as Rauðrblade+ or Unity Blooms+.

Low Def and Res Make Him Fragile

Erk has low Def and Res, which makes him vulnerable against any unit that attacks him.

Make sure you watch out where he is positioned after he's done attacking, or use a dancer to make him retreat to safety!

Erk as a Source Hero

All of Erk's skills carry Inheritance Value!

All of Erk's skills carry inheritance value as everything can be inherited from him. Just make sure to consider all your resources as all except Moonbow are quite rare. You can also get Moonbow from him if you desperately need him. Since he is a demote unit, he is not that powerful compared to his batchmates and it is not an uncommon sight to get multiple copies of him.
