The odor of a smelly shower drain can be eliminated by removing debris from the drain. Discarding the odor-causing material in the garbage outside the home ensures the smell does not invade other areas. Boiling water dissolves oils and grease deposited on the sides of the pipe in the drain, which add to the smell.
Luckily for us, Nernst derived an equation that allows us to determine at what point the two forces (chemical and electrical gradients) balance each other - in other words, at what point we have an ionic equilibrium.
Nern is a fairly useful support ally, in addition to healing HP and inducing fear and sleep, he has the unique abilities to also recover SP and TP. This means that Nern is capable of replenishing his own SP endlessly so he can use his support moves for even the longest of battles.
