The Templar [Unseen Offensive]

Ok? That’s nice. But the thing is, 241 requires that the assassin isn’t:
Occupied
Jailed

While, if you anticipate that the Assassin might be one of those, you might want to use it.

“adding kill power to a convert is bad”
“but what if they get prevented from using it”

that doesnt change the fact that it’s probably bad design

I’m saying that it can also be used to hide the assassin if they are prevented in some way.
