Billy Kid's Stat Priority

When building Billy Kid, CRIT Rate/DMG are the most important stats to focus on, and afterwards you want to focus on building up more ATK with Billy.

Billy Kid's Skill Priority

Billy Kid's most important skill to level is his Core skill since it provides an important increased DMG bonus. Just as important is his Basic Attack because that is what you will be using most of the time to deal DMG, so you want it maxed out.

How to Play Billy Kid

Billy Kid is mainly focused on dealing with large crowds of enemies dealing Physical DMG in a large radius by shooting down targets while keeping a distance.

While holding the Basic Attack button down:

• Enter Crouching Shot to extend the duration of the attack and increase his DMG by 25%.
• Move during Crouching Shot to enter Rolling Shot and increase his Dodge Counter DMG by 25%.
• Release the Basic Attack button to launch Finishing Shot, a powerful attack that deals heavy Physical DMG.

Billy Kid may be a ranged shooter, however, his attacks do less damage when far away. His optimal damage will be between close range and 3 square tiles (in the training room). Over 3 tiles he will gradually do reduced damage:

• 75% of his optimal damage when over 3 tiles away
• 50% of his optimal damage when over 4 tiles away
• 25% of his optimal damage when over 5/6 tiles away
• Over 7/8 tiles away in the training room some of his attacks will completely miss the targets.

These modifiers apply to his basic attacks, special and EX special attack, and dash attacks. His ultimate is not diminished but at a too high range it will miss completely.

In order to play Billy, you will have to position yourself in a way that will always put you in the optimal range. You can use his Rolling Shot to reposition yourself.

Cancelling a crouching shot early with an Ex Special Attack or Ultimate will Still apply the crouching shot buff.

Billy's rotation goes as followed:

• Enter Crouching Shot
• Activate your Ex Special Attacks
• Dash forward or spin attack to reposition yourself closer again
• Finish off with the Ultimate

This way, all the attacks have Billy's passive buffs applied.

Overall, Billy is a good Agent that you get for free at the beginning of the game, allowing you to have a team member that has the ability to take down large crowds of enemies in a short time, as well as focusing on bosses with heavy damage, making him a good choice to clear content early in the game.

Billy Kid's Best Mindscapes

Billy Kid's Mindscapes are overall good. His M1 grants him some nice Energy Regen, and his M2 and M4 provide with increased DMG and CRIT Rate buffs respectively. Billy's M6 is definitely the best one since it grants him a massive DMG bonus.
