In this guide, I list all evolved skill combinations in Rina’s Undercover Train Operation. These evolved skills are important because some of them are also required for hidden achievements. To unlock an evolved skill, I need to fully upgrade both required skills first. After both skills are maxed out, the evolved version can appear in the draw.
Evolved Skill Combinations
Evolved skills are created by combining two specific skills. There are 6 evolved skills in total, and each one requires a different pair of maxed-out skills.
Once I max out both skills in a combination, I become able to obtain the evolved skill from the draw. Because of this, it is better to focus on the exact skill pairs I need instead of upgrading random skills.
Detection Master
- Intense Focus + Keen Eyesight
Effect: Awareness skills are always active. This can also be combined with psychic awareness skills.
Psychic Master
- Intense Focus + Psychic Perception
Effect: Psychic awareness skills are always active. This can also be combined with standard awareness skills.
Mass Arrest
- Nimble Movement + Skillful Arrest
Effect: When I arrest one groper, all gropers within range are arrested at the same time.
Sensory Block
- Concentrate + Cooldown
Effect: This is an active skill. Arousal does not increase for 5 seconds. The cooldown is 90 seconds.
Hunter
- Skillful Arrest + Leg Sweep
Effect: Gives a 0% chance of arresting a fleeing enemy.
Path of Foresight – Enhanced
- Foresight Cooldown Reduction + Path of Foresight
Effect: Foresight is divided into three categories: upper body, crotch, and butt.
To get every evolved skill in Rina’s Undercover Train Operation, I simply need to max out the two required base skills for each combinations. After that, the evolved skill becomes available through the draw. Since some hidden achievements may require these evolved skills, completing all 6 combinations is useful for achievement hunters.
