Some of the Blue Slimes attack can apply Paralysis and it can last a few turns, but I think it might be able to stun lock you by overwriting the duration if it is reapplied when already affecting you. Slimes always come in the troop of three. The preferred way to beat them is supposed to be either using Ice Magic or physical attacks granted by the Martial Arts or Arms skills. Their Agility is very low so you should almost always act first in a fight and due to a low health pool the Slime should drop from one or two attacks. Using gear with Resilience stat should minimise damage as well.
As I mentioned before, Flax Seeds and Forest Seeds can't be ground into regular Oil, you have to use stuff like Potato Seeds, Saffron Seeds, etc... basically any seeds which are not Forest or Flax.
The suggestion for making the Hero miss hits if he has the Pervert trait is pretty interesting! I'll see if there is an easy way to implement it and if there is I'll add it in next release, otherwise I will have to work on it some more and it will appear later.
