To find a Sicario’s Skills you’ll want to open their information window and scroll past Talents and Expertise Level. Here you can view their already active Skills and set new ones.
Skills provide additional benefits for your Sicarios. They can be obtained from Skill Chests (which can be bought in the Shop) or as a reward for completing Special Events (when available).
When you increase a Sicario’s Expertise Level using Expertise Cards (these are obtained through leveling up your Sicarios), you’ll be able to open more Skill Slots to make them even stronger!
To convert/upgrade Skills or activate bonuses, you’ll need to open up your Workshop and choose the Skills tab (the second one on the left).
