Pirate Era battle tier 1

I saw all the complaints. I promptly geared up my three pirates, upgraded the abilities, no zetas and only some omegas, and went into the battle. I completed it the second time around with an unmodded Kix, a 147 speed Quiggold and an half-good Ithano.

Why is everyone having a problem? Ithano almost one shots KRU, he is definitely not “full healing” as I’ve seen others claim.
