did volt get a buff or is this a bug

[skull755]

so i was playing around with my volt prime build when i noticed something weird and that was that he had 110% power duration as his default stat. i don't own normal volt so i cant tell if its just the prime that has this. can anyone tell me if this is intentional until now i thought that nidus was the only frame with a stat like this

If your shields are also lower it's probably this arcane.
