I’m trying to use Vaion’s Chariot with teleport which has the nova cast.
But, the damage do not seems to be “more”. It works as intended or is this a bug ?
The Ele Nova cast from the Teleport nodes wouldn’t inherit any damage modifiers from Teleport. Generally if a thing can be put on your skill bar (like Ele Nova) then it won’t inherit any modifiers from something else that procs it (such as Teleport in this example).
So no, this is working as intended.
If Teleport had its own damage (like Transplant or most other movement skills do), then that would inherit the damage modifier from the boots.
