Updating the scaling chain.
Baseline 7-C AP via meteors (7.41 KT) -> 25% yadda yadda with upgrades (9.26 KT) -> Flame body amps [dmg up to 40% higher] (up to 12.96 KT) ->
46.69 KT supporting feat for volcanic eruption -> 25% yadda yadda with upgrades (58.36 KT) -> Flame body amps [dmg up to 40% higher] (up to 81.70 KT) -> Various other spells that are much stronger than Volcanic Eruption (quite a decent bit higher than previous that) -> 25% yadda yadda with upgrades (even higher) -> Flame body amps [dmg up to 40% higher] (even higher than the previous) ->
{Durability scale start} 25% yadda yadda defense with upgrades (Upscales massively from 102 KT) -> 40% defense with rock armor (Upscales massively from 142.97 KT) ->
50% DR when blocking (Upscales massively from 214.46 KT) {Durability scale end} -> (AP or Dura may not applicable from this point on but I thought it'd help)
312.48 KT ED nuke -> 25% yadda yadda with upgrades (390.60 KT) -> Flame body amps [dmg up to 40% higher] (up to 546.84 KT).
I may do the speed scaling chain later as player does have speed amps, although I don't know by how much they get amped.
