Every time when there is a recommendation, a group of people come forward to scold; it's the same this time, and the scolding is inexplicable. The author has now found that neither explanations nor arguments work, as they know only to scold; it's unclear whether they're trolls or vested interests under aliases. Now, reading comments affects his mood too much.
Enchantment Potion is indeed useful, but its effect is too strong; there is a high possibility that one who gets affected could be bewitched to death. Therefore, using this is not as good as using poison directly.
The key point is, this type of potion cannot be smeared on weapons at all, it can only be thrown. But in this way, very few will be affected. If it were to be smeared on weapons, it's like smearing a layer of glue on the weapon.
The drug properties of the Enchantment Potion are very strong, but this greatly affects the use of the weapon.
