Description:
Allow players to reroll a single individual enchant of these weapons. So that, if the player wants to change only one enchant, they can reroll it instead of resetting and re-enchanting both slots.
And ideally, the cost for reroll should be lower than the initial enchant process. But if that's too much, it's also fine to keep the reroll cost same as the enchant cost for that slot.
Why is this a good idea?
I think the current system was fine for dimension weapons, since dimension weapons are very cheap to make and we could simply make multiple weapons with different enchants for different occasions.
But time gap weapons are very painful to craft and refine, it's not realistic to expect players to go through that process multiple times. So I wanted to instead suggest making it more convenient to change the enchants of these weapons. Basically I don't like having to hard-commit to race/ele-specific enchants like those and being stuck with that choice.
Crafting/refining a time gap can easily cost around 1.5b, and enchanting them would cost another 150m at least. Which is fine, but I think that's enough, there is no need to take another 150m cut for each time someone wants to change those race/ele-specific enchants. In my opinion it'd make more sense for the re-enchant process to not cost as much as the initial enchant (although it should still cost a decent chunk), I don't like how it currently works.
What risks or downsides does it have?
Maybe less zeny sink for the server. But the opposite may be true as well, since this'd make people more likely to re-enchant their weapons, increasing the frequency of use & zeny spent.
Additional Info:
I mainly suggested this for the time gap weapons, dimensions were only included because they share the same enchant system.
