I've been doing a lot of testing with the cooking skill tree and it's pretty terrible. For those interested, I created the video below to showcase what the unthinkable delicacy does and my thoughts on it. TL;DW - it buffs your vitamins and food/water. That's it! It costs 41 skill points to get up to the unthinkable delicacy. That's the same number of points needed to get the mortar in the artillery tree. Many of the other cooking skills give you buffs but also give you debuffs at the same time, making the required skill points and ingredients not worth the hassle. I think cooking needs to be reworked from the ground up. Perhaps we can get more meaningful buffs, or keep the current buffs but make them last 6 hours instead of 10 minutes.
