Boril is an ok tank.
But that’s not what he’s best at.
Me too. I used him early on, then stopped for a long time.
Until he got un-shelved.
This.
Why I use Boril every day
Context: I raid in high Platinum to low Diamond (2250-2600 cups), and open nearly all of my chests in Diamond now.
I have few 5* heroes. Evelyn at max, Leonidas and Thoth-Amun at 3-70, and Vivica at 3-61 on her way to max…in the month that will take.
But the Defense Teams I face are chock-full of 5* heroes. Including plenty HOTM.
I usually have a 400-800 tp gap between my team and the teams I routinely beat. For me to win raids, I have to stack, usually 3-2.
For every red tank, Boril is definitely in my blue stack.
Obviously his attack isn’t why — it’s because Perfect Riposte on Offense is killer, especially against AoE hitters.
Many a Zeline, Isarnia, Quintus, Azlar, and Elena have suicided themselves on my Boril.
And he can prove useful with target + nearby hitters or even snipers too.
Paired with Grimm and Sonya or Triton (depending whether any of the heroes have buffs), along with Proteus and (usually) Rigard, he’s part of an effective killing team.
So I’d suggest considering Boril not for Defense — but Offense.
And for what it’s worth, I’d say that’s true for Captain of Diamonds too — much better suited to Offense.
