Acadian, thank you, that was a magical morning in the woods!

As far as I know the enchantments do not apply to every strike, and neither does poison. Putting poison on the weapon suppresses the enchantment, but I don’t know how that works as far as using up the weapons’ charges. I suspect that an enchanted weapon’s charge would not be used while a poison was equipped on the weapon, which could save on soul gems. This is something I’m curious about as well, since Jerric runs through a ton of soul gems and often does not need the extra boost from the weapon’s enchantment. He gets a lot of grand soul gems from his adventuring and greater soul gems from Darnand’s Enchanting writs, but he hates to waste the energy.
So I think that a Charged-trait weapon would have an increased chance to apply a status effect such as the chilled/concussed/burning secondary elemental effects, while an Infused weapon would have a reduced internal cooldown for applying the enchantment effect such as frost/shock/fire, perhaps 3 seconds instead of 4 seconds.
I am still in the dark as to how the applied poisons work with weapon traits. I think it would depend on if applied poison (meaning from Alchemy and not a poison enchantment) is a status effect.
