This is long overdue, but here it is, a question determining the usefulness of the Quicken enchantment on items.
As stated in this link, the Quicken Enchantment is gained by killing a Runnark, in this case with an item. Once gained by an item, the Quicken Enchantment will cause an object to move 12% faster than an unenchanted but otherwise identical object when acted upon by a given force. (Maxed out, the Quicken Enchantment causes an object to move 10x faster instead of 12% faster than an identical object lacking that Enchantment when acted upon by a given amount of force.)
Please note that while this makes it easier to make an Enchanted object start moving, it doesn't make it any easier to stop said object. Think of it as a train; once it's picked up steam, it gets harder and harder to stop.
This Enchantment also negates the increased drag, friction, wear and tear, and impact forces an object would experience due to its heightened speed. This Enchantment channels and magnifies the kinetic force going into an object, making it travel faster with less force. This will (most likely) be useful for:
1. Serrated Weapons-Serrated blades are more damaging but cut much slower, and are also more likely to get stuck and whatnot. This question pretty much sums up the disadvantages of serrated (edged) weaponry, but I'm curious as to whether the Quicken Enchantment will make them more feasible for combat.
2. Melee Weapons (in general)-Quickened melee weapons strike me as a potential liability because they will travel faster given the same amount of force as a regular weapon. So while they'll hit faster (and potentially harder), they'll definitely take some adjustment to wield properly.
Quickened javelin? Thrust too hard, and you'll dislocate your shoulder, maybe even fall over from the inertia. Pull on your stuck spear too hard, and you'll go flying backward.
Quickened Warhammer? Careful lifting it off the ground, or you may find it swinging up into your face!
And let's not even mention what happens if you throw too hard!
3. Thrown/fired weaponry-The faster a projectile travels, the harder it hits. Plus, in conjunction with the Boomerang enchantment, this should enable rapid-fire due to the ammunition's quick return. However, the weapon itself would not be firing quickly, unless someone had killed a Runnark with the weapon firing the projectile itself. Sling, atlatl, bow, or musket-it doesn't really matter, 'cause chances are it can't be done often. They're built for ranged attacks, not melee.
4. Mechanics-Pulleys, for example, would be benefited by the Quicken enchantment, which would make it easier to lift heavy objects faster. My tech level is early Renaissance at the most, so I'm not sure how much can be done here, especially since the mechanical parts need to be able to kill a Runnark to gain the enchantment. Enchanting the raw materials is doable, but will likely give your architects fits....
5. Transportation-I'm sure transportation will be benefited by the power of Quickening, it's just common sense. However, in medieval times, transportation wasn't exactly sophisticated, being centered around boats, wagons, carriages.....these things are sped by what's pulling them, so they'd have to modified for pushing, and then the Quicken Enchantment might make them rush ahead of whatever's pushing them or other nasty possibilities.
I'm sure there are other options, and that I may have missed an important possibility or two, but that's why I'm asking this question: What Benefits Would The Quicken Enchantment Have On Items?
The best answer should start with a shortlist (summary) of what items or kinds of items would be benefited by this Enchantment and why. (If you've included one or all of the categories I put above, minimum explanation is necessary).
They also should have separate categories, or groups of, items that would be benefited from this Enchantment.
Each category of item that would be benefited by this Enchantment must be thoroughly analyzed to determine how beneficial the Enchantment would be overall on items in that category.
