Exciting update, really like how this is shaping up. Agreed that giving each merc their own signature thing is a great way to make them more distinctive, which is pretty core to the JA experience.
What does a mishap mean with thrown explosives? Is this similar to accuracy, or more variable outcomes like going boom in merc's face or being dropped at their feet? In the screenshot with Fidel, it says "Mishap Chance: None". Does he just throw a perfectly accurate grenade every time? That would feel kind of off for the balance of that skill, and the general JA feel, where nothing should always be 100% guaranteed.
Damage of a grenade also being affected by explosive skill feels a bit weird, unless the merc had some hand in crafting the device.
