How bad is starving?

[Rasit]

[...]So now I am wondering how bad are the effects.[...]

I made the mistake of attacking a marsh with a supply lowering death site, to make matters worse I accidentally hit e instead of r, twice!

This was my small strike force before (they won this fight easily).

This was some turn later after the little swamp vacation, they were joined by the Inquisitor and the Angel after the previous battle.

Since everyone got a disease I was forced to get them in a battle every 4 turn, luckily I had a regeneration bless.
