I'm curious how people think a character in this predicament would be penalized with regards to combat. Obviously they couldn't get up to a full run with that lead length and with a chain around one ankle. I think the closest point of reference in the condition summaries is Entangled which is basically a -2 penalty on all attack rolls and a -4 penalty to Dexterity. I'm not sure that's appropriate given that the character is only bound at the ankle.
I'm curious what people think of this and if such a penalty seems fair or unfair or otherwise. I have looked online and through a few resources I have but I can't seem to satisfy my thoughts on the matter.
