This patch also adds the Elation Path for the Trailblazer, as well as two new 5-star characters: Silver Wolf LV.999 and Evanescia.
Welt’s Novaflare buffs
His Basic ATK and Technique are not getting changed.
This update undoes a little bit of the Nihility powercreep that has happened over the years. Now, he is a more viable option on some teams like Acheron. However, his newfound strength also makes him a competitive choice as a DPS.
If you’ve been pulling other Nihility units, though, there are better choices than him.

- Now Bounces a total of 5 times, up from 2.
- Total Energy Regeneration is unchanged (30), but the Energy per hit goes down (10 >>> 6)
