Rating8.0 / 10

Helena is one of the best support in the game among the ★4 servants pool with her abilities that make her comparable to the infamous Waver and Merlin. Even though she does fall off slightly compared to the other two due to the difference between 4 Stars and 5 Stars, it is still a very useful servant that should not be neglected if you managed to get your hands on her.

Pros

  • NP with multiple debuffs. Helena’s NP comes with three different debuffs that would be applied to the enemies upon hitting them which are decrease in the enemies’ defense, critical chance and debuff resistance. Even though the damage from the NP itself isn’t that high even after the Interlude upgrade, the debuffs applied could be very useful for the party in terms of offense and defense.
  • Support specialized skillset. Besides charging up her party’s NP gauge using the Magical Tuning skill, Helena has arguably one of the best support skill in the game right now, Pursuit of the Unknown. It is a 20% damage boost across every card types except Extra card which also comes with additional star generation and NP gain, allowing her to fit in almost every party as a support but works more effectively within an Arts party due to having an Arts type NP and three Arts cards in her command cards deck.

Cons

  • Doesn’t work that well by herself alone. Although Helena is a support that can provide her party with lots of burst damage potential, she won’t be able to get much things done without a strong attacker as her own damage is quite weak. Besides that, she also faced competition for her support slot with Merlin and Waver around which are more popular due to their 5* servant status.
  • Long cooldown time for skill. Helena’s skills are very good for supporting the party but they come with the demerit of having a very long cooldown period with the lowest at seven turns at max level. Therefore, players should always take into consideration of this weakness when building a party for battle that is going to last for a long time.

Strategy and Tips

Helena is a support role servant that helps to increase the damage of her party members using her Pursuit of the Unknown skill that covers all types of servants, be it Buster, Quick or Arts focus. Besides that, she can also provide NP charges to the whole party and generate small amount of critical stars every turn with her Mahatma skill.

Noble Phantasm

Helena’s Noble Phantasm, Sanat Kumara is an AOE NP that would debuff the enemies after the damage has been done. The decrease in enemies’ defense would allow your party to deal more damage to them while the decrease in debuff resistance would make it easier for stun effects to get through. Besides that, it also has a defensive usage by decreasing the critical chance of enemies to reduce the chance of getting killed accidentally by criticals.

Best Servants to Work with

ServantExplanation
Tamamo no MaeTamamo no MaeWorks well together as double support for the party as Tamamo’s NP helps to overcome Helena’s weakness of having long cooldown on her skills. As both of them are Arts focused servants it is suitable to choose a third member that has the same trait also for attacker such as Vlad III or Nero Claudius (Bride).
Ramesses IIRamesses IIAs Helena’s Mahatma skill that increases her NP damage has a 80% success rate at max level, Ozy can help to increase it to 100% with his Protection from Ra skill that increases the success rate of servant skills for a turn. Besides that, as a Rider class himself he is able to make use of the critical stars provided by Helena to dish out heavy damage.
Elizabeth Bathory (Halloween)
Elizabeth
(Halloween)
As Elisabeth herself also have skills that generate critical stars, they can both be used together to feed servants that are hungry for critical stars such as Drake.

Skills

Upgrade Priority

1=3>2

Both Helena’s first and third skill should be leveled simultaneously but the priority can differ between whether you would prefer fixed amount of NP charges or an increase in all the command cards’ performance which would also increase your servants’ efficiency at building up NP gauges. The second skill has a lower priority than the other two as five critical stars per turn aren’t that much and the increase in NP damage buff has a chance of failing even at max level.
