Key to the Heart (Steel)

Guide

Steel is a tricky type to build since there's no type-related support, only Charge and Tank cookies. However, this doesn't mean that Steel is useless, since Hollyberry can fill the Steel meter faster than any other Steel type.

With the right teammates, Hollyberry can do over 200 million damage to the boss during its resting phase. So, let's go over this team.

Hollyberry will be your main attacker for this phase. As mentioned above, she fills the steel gauge faster than any other Steel type. When combined with Supports that compliment this trait, she can quickly tear apart the Boss' HP which will lead you smoothly to the final phase.

Cream Puff and Okchun act as Catalysts to Buff Hollyberry's damage even further. Make sure Cream Puff has at least a +10 Magic Candy.

Linzer is a must for any boss fight, as no bosses are immune to her Suspect debuff.

Pavlova is a backup attacker that deals great damage and is immune to the boss' sleep attacks. Should Hollyberry fall asleep during the fight, he will keep attacking the boss and buff CRIT% for your team.
