Rosita doesn't back down from a fight. No battle is too tough for her relentless fighting spirit. She has the following Leader trait:

Fighting Fury (FF)
If there are enemies adjacent to Rosita on her first main attack, she gets an extra attack(s) afterwards. She gains an attack for each adjacent walker, up to {X}, and {Y} if she is the leader. Each extra attack does {Z}% of the main attack’s damage.

After the main attack, Rosita can also choose to move away for half an action point, instead of dealing the extra attacks.

As a leader, all melee classes gain this bonus.

Notes:
• The enemy that you attack also counts into the extra attacks if they are in an adjacent space when you attack
• Bonus charge attacks, as well extra attacks from various traits, can be used to move and attack in between FF attacks
• Extra movement from Tactical is possible to use in between any attack or after, as long as Rosita doesn’t move before the first attack. However, using this movement will end her turn, no matter how many FF attacks are left
