How do I compare a different value based on object in a family?

Hi! New to the software, learning the ropes.

In this code I've set the Enemy to Punch if the attackOdds are less than 5.

However, I'd like this number to be different for each type of Enemy, so I want to avoid hard-coding that 5 and use an expression instead.

The problem is that the Condition of the Enemy only allows me to select Family Instance Variables.

Does anyone know the best practice for this please?

Okay I've ended up writing this code and it seems to work alright:

(Worth noting that Ken is a sprite in the Enemy family)

If anyone has a better way of doing it, please let me know. Thanks!
