First, I would like to mildly disdain those who refuse to share information and tell others to try it themselves! What age are we living in? We need resource sharing!
The character you should choose is Dana. (This doesn't even need to be said, only Dana has the innate skill to make claws.)
Dana's forging skill description can be seen in the picture:
First, how to forge the Lightning Spike: Buy a one-handed sword and upgrade it four times. The name will then be called the Sacrifice Shortsword, as shown in the figure:
After forging, there will be a 10% chance of turning into the Lightning Spike.
There is also a 10% chance of becoming a lower-level ordinary claw, and an 80% chance of becoming a same-level ordinary claw.
Now let's talk about how to forge Shadow Lament.
First, you need to obtain an unnamed short sword (PS: This sword is at the same level as the Lightning Spike), meaning that when using this short sword for crafting, there is an 80% chance of crafting it into the Lightning Spike, a 10% chance of crafting it into Shadow Lament, and a 10% chance of crafting it into a lower-level ordinary claw.
The source of the Unnamed Short Sword: [Boss] No.6 [Phantom Ranger] Death Shooter
Equipment drop rate and probability:
(Also, I'll include the drop rates for other equipment from this monster here)
To craft Shadow Lament, there is another sword called Dananx's Sword.
The monster that drops this sword is: [Boss] No.7 [Salamuto - Sword Saint]
Equipment drop rate and probability:
It is rumored that this sword has a 100% chance of being crafted into Shadow Lament.
However, personally, I think it should only be 90%. This sword should be at the same level as Shadow Lament, with a 10% chance of dropping down one level to become the Lightning Spike. There is a 90% chance of being crafted into Shadow Lament (10% chance to upgrade, but it cannot go higher since it is already the highest). This specific claim needs further verification. Next time, after I test it through single-player SL, I'll let everyone know! After my own single-player SL testing, I have confirmed that Dananx's Sword can be crafted into the Lightning Spike, with a probability of around 10%!
Properties of the Lightning Song Set:
+35 Attack Power
+255 Life Points
+10% Attack Speed
Electric Fury duration increased by 15 seconds (Skill duration when Electric Fury recharges to 100%).
