Subj, this awesome skill somewhat lack dmg . I suggest for adition of extra synergy with lightning dmg around skill lvl 32 with base dmg 16, scaling up to 200 dmg at 12/12 and to 330 at ultimate rank.
Aslo, burning dmg from inferno is kinda useless, so no one ever level it beyond one pointer. Perhaps its better to switch it to chaos dmg?
Callidor’s Tempest is fine as it is now I think. It doesn’t need buffing.
Inferno might be a bit underpowered but the main skill definitely is not.
I don’t think Inferno is worth even 1 point because of the energy cost.
Wrath of Agrivix is underpowered too, especially since so many difficult monsters have complete immunity to knockdown. If it gets a large boost to AoE it might be worth it.
T_T no love for Calidor tempest.
