Brynhildr is a damage-dealer Lancer with some supportive capabilities. This makes her a rather flexible Servant, excelling at neither damage nor support but possessing both functions. Other Servants, such as Karna, may benefit from her third skill, though in the lack of another powerful damage dealer she can use it for herself. His second skill’s NP damage reduction is rather situational; however, the critical chance debuff can be rather significant in harder battles.
As she is not a dedicated damage dealer, her maximum performance in an optimized team is rather low when compared to other strong contenders from other classes. Fortunately for her, there are not that many competitors in the Lancer class, making her still one of the more favorable Servants among her peers.
With the addition of her 2nd interlude upgrading her 3rd skill. Brynhildr becomes a much more viable offensive servant. The star absorption buff increase allows whoever receives it to benefit more from the few critical stars Brynhildr can generate with her 2 quick cards. The biggest addition is the critical damage bonus which scales quite high, actually making this a superior version of Jeanne de Arc Alter's Self-Modification skill.
Pros
Good NP gain and critical star gain rate.
Decent survival due to second and third skill.
Can act both as a primary and secondary damage dealer.
Cons
Mana Burst percentage is lower compared to other Servants.
NP’s supereffective bonus is situational.
Second skill rather situational.
Strategies & Tips
Brynhildr can be used as either a main damage dealer or an assisting one. Due to her decent star generation and targetable critical absorb buff, she is useful as a partner for Servants such as Karna, and the heal as well as her second skill also help with general survival. As a primary damage dealer, she will be rather sturdy, owing to her high base HP and the heal on her third skill.
Noble Phantasm
Brynhildr Romantia is a single-target Noble Phantasm, with increased damage against Servants with the ‘Brynhildr’s Beloved’ trait. Being single-target, it deals a good amount of damage even with Bryn’s relative lack of offensive buffs, even more so when hitting the appropriate target. The star generation effect is particularly significant for Quick-based critical teams. Thanks to her good base NP gain rate, Bryn can unleash this NP rather often.
Buster Performance These Craft Essences maximize Bryn’s performance as a damage dealer. Although it stacks additively with Mana Burst (Flame)’s Buster up part, their effect is still highly significant.
Critical Damage These Craft Essences offer large benefits if Brynhildr is to be used as a main damage dealer in a critical-focused team. However, do note that some supports may have huge critical buff percentages, which would hurt the damage scaling for these CEs.
Combination Combined effects tend to give greater effects compared to pure ones when both are applied. The fact that one of the effects will always scale multiplicatively with outside buffs is also welcomed.
As usual, Zhuge Liang’s NP charging effect is always welcomed. Additionally, he also possesses attack and critical buffs, both of which Bryn lacks. The defense buff also makes Bryn’s heal more significant.
Karna is the Servant who benefits most from Brynhildr’s third skill. Using Bryn allows Karna to bring other CEs instead of critical absorption ones, and thus increases his damage potential greatly. Her good star generation, coupled with the buff from her Noble Phantasm, is also highly beneficial.
With constant critical star generation, attack and critical buffs, as well as defense buff and heals, Hans is a perfect companion for Brynhildr. His buffs allow Bryn to deal much heavier damage, while aiding the team’s sustain.
With his insane buff percentages, Merlin manages to overcome Brynhildr’s biggest weakness. His critical debuff stacks with hers, and he also provides critical stars per turn via his Noble Phantasm, allowing Bryn to land critical hits much more reliably.

Upgrade Priority
Mana Burst (Flame) B
Despite the lower percentage, Mana Burst (Flame) is overall still a very formidable skill. This skill should be Bryn’s first priority, to let it keep up better with her NP gain.
Primal Rune
While critical chance debuffs will be of increasing importance against later bosses, it is still rather situational. With the NP damage reduction being rather insignificant, this skill should generally be leveled last.
Hero’s Bridesmaid C
Brynhildr’s unique skill, Hero’s Bridesmaid grants Brynhildr a rarely-found flexibility. However, as criticals are not always reliable, Mana Burst (Flame) should still be her first priority, though this skill makes a rather close second.

Bryn’s QQABB deck allows her to produce a decent amount of critical stars, while the lack of Arts cards doesn’t really impair her thanks to her decent base gain, though it may affect the team’s NP gain as a whole.
It's still a good debate about who's stronger between Scathach and Brynhild, mainly about damage and survivability. In the latter, though, Scathach seems to have more edge because one of her skills include a 100% dodge for one turn, while Brynhild is decreasing the enemy's strength and critical rate.
Also, the Healing level of Hero's Bridesmaid (Skill 3) raise the Healing amount so it can practically replace the Heal command spell, so sometimes it's also getting priority over Primordial Rune. Depending on the situation, it may have equal priority (but both are still below Mana Burst (skill 1)).
