The plan is set for the next five months and I should prepare for that.
These skills that I want to improve can't be improved easily. Most skills can be improved through normal training but some need to be improved by fighting enemies or using some special means.
For example the Poison Resistance. It could be improved as you fight against enemies that have poison skills but these are pretty rare. Moreover, fighting them head-on without having resistance most probably would lead to death.
So the best way to improve poison skills was by injecting poison into the body. The amount should be small and the poison's potency should be low. There should be Antidotes nearby or else there is a chance that you may die.
Poisons are the most deadly way for one to die.
Death means corrosion of the meat suit we were wearing. When important organs are corroded to a degree, death would be inevitable. Out of all, poisons are the most potent way for that to happen.
