Karna boasts a high attack stat, which when coupled with his Mana Burst (Flame) skill makes him a powerful damage dealer. He also possesses a critical-enhancing skill in the form of Uncrowned Arms Mastery, which allows him to deal large amounts of critical damage as well as generate quite a lot of critical stars. Additionally, his first skill is a decent crowd control tool as it seals the target’s natural NP gain and NP usage for one turn.
However, his damage potential is severely limited by the fact that his third skill does not have a built-in critical absorption buff. As Lancers have an innately lower-than-average critical weight, this makes him unable to make the most of his otherwise-formidable set. Additionally, his Noble Phantasm is rather plain, and though it deals a good amount of damage against Divine opponents, being unupgraded, Vasavi Shakti will often find itself losing in the damage competition against other Servants’ Noble Phantasms.
Pros
High base attack
Great critical damage, decent critical star generation
NP seal skill
Cons
No critical absorption skill
No survival function
Low NP damage [Removed Post-Upgrade]
Strategies & Tips
Karna can generally be used as a decent standalone Lancer; however, to make the most out of his set, it is best to use him with two low-critical weight Buster/critical supports, so that he is able to perform critical hits more consistently. A critical absorption Craft Essence is also recommended for Karna.
Noble Phantasm
Vasavi Shakti gains increased damage against Divine opponents. However, aside from this, it has no other gimmick, and since most other Servants have gotten their Noble Phantasm upgrades, it makes Karna’s NP a rather weak one comparatively.
[Post-Upgrade] Thanks to the upgrade, Vasavi Shakti is no longer afflicted by its formerly low damage, bringing it to equal standing with other AoE NPs. The Buster Resist Down adds to Karna’s great offensive prowess, which is always a good thing.
With low critical weight, offensive buffs, instant NP gain, and critical stars per turn, Merlin is an obvious choice for Karna. As with most others, Merlin turns Karna into a monstrous damage dealer.
Zhuge Liang’s attack buff is multiplied with all of Karna’s buffs, making it extremely potent. His instant NP gain also aids Karna in performing NP Brave chains, and the critical buff is always welcome. Additionally, being a Caster, Zhuge Liang has a lower star weight, allowing Karna to gather more stars.
Hans possesses everything Karna needs; that is, critical stars, offensive buffs, and defensive assistance. Due to being a Caster, his low star weight allows more stars to be allocated to Karna’s command cards.
Nightingale, being a Berserker, adds to the team’s damage output overall. Additionally, her Buster buff skill allows for Karna to hit much harder than normal. However, one of the defining factors is her nonexistent critical weight, which allows Karna to perform more criticals.
Critical Absorption Up / Combination These Craft Essences cover Karna’s greatest weakness, and allows him to compete with other Servants in the critical damage department. Generally speaking, these Craft Essences with additional effects (such as critical damage up) are better than pure absorb CEs.
Starting Noble Phantasm Imaginary Number To be used in battles where Vasavi Shakti is needed early on; that is, on fast-paced fights against Divine enemies, Archers in particular.
Buster Performance Up Further increases Karna’s damaging potential. These Craft Essences should be used instead of Critical Absorption Up CEs when Karna has no access to critical stars whatsoever.
When equipped on Karna, Increase Quick Card, Arts Card, & Buster Card performance of all allies by 8% while on the field.

Discernment of the Poor A
As the most important part of this skill - the NP seal - does not scale with increased skill level, this skill should only be leveled last, and only for the cooldown.
Mana Burst (Flame) A
As this skill has combined effects, it give slightly more bonus to Vasavi Shakti compared to normal Mana Burst due to how buffs of different types are multiplied. However, its effect is less on Karna’s other command cards. Still, this is his most reliable damage increasing skill, so it should be the first to be leveled.
Uncrowned Arms Mastery
Due to the NP gauge increase, this skill is an useful one even when Karna has no access to critical stars. However, due to the unreliability of this skill, it should be leveled after Mana Burst (Flame), unless a reliable way to make Karna perform a critical is readily available.
Discernment of the Poor A
Available from the start Reduces one enemy's debuff resistance for 1 turn. Prevents them from using their NP for 1 turn (this also prevents the enemy from gaining NP charge).

While Karna’s QQABB deck may present an NP gain problem for other Servants, Karna’s decent base gain coupled with his third skill makes him largely unaffected by this. Instead, it increases the effectiveness of Uncrowned Arms Mastery’s critical star gain bonus.
