Those are not really evolutions. It's like...just new versions of old cards, dunno XD

Also you get Hero and co. while playing main story, Patricia is obtained via various events others are event gacha.

Anyways:

1. Hero's skill is aoe

2. Touka's skill is aoe. Her critical rate increases by 10% (1.5x→1.65x). Also her 2nd ability is something like: "When a warrior other than self uses an active skill, Touka's special gets 100% boost (6x→12x) and she takes 20% less damage during 10 seconds". I have her myself so I can confirm if you need XD

3. Big bro can inflict stun with normal attacks. Also his 2nd ability activates when another warrior except Haru uses a skill. Unsure about the % but his critical rate becomes 1.75x, probably around 15-16%?

4. Vienta grants Soul-Island-affiliated warriors increased critical rate and archers from Soul Island are granted an ability to slow with normal attack.

5. Isaiah has 30% drop rate boost, if it's important. Sorry, Nimpha.

6. Faceless shoots arrows to a column one square in front of her. The same special as Lucrezia but it's closer to Faceless.

7. Patricia's skill is 9x.

8. Minimo shoots a missile and then a certain % of damage dealt by the missile is converted to heal. It's burst heal.
