Hey there, Ich reached level 3 in desolation. so for the first level up i skilled building and for now i can build level 2 houses. for my next level up i wonder what i should skill and i decided Medical Progression. I have a big grey medical toolkit with insuficent uses. so i skilled level 1 medical and tried it, but i am still not able to use this. I found out the painkillers now give me about 20% blood. they havent done this befor medic level 1 i think. Is there any guide or explanation thread for the skill system, this would help me much.
