So unless I've made some mistake with maths, level correction penalty seems to start lessening again, values for level 78 are consistent with level correction being at least 0.84, instead of 0.83 like it was at 75.
BLU math ahead:
Naked, no MAB trait, using Firespit. 64-1 INT, 56+5 MND, target is Tiny Mandragora (6 INT), 57 dINT.
57*1.5 = 85 damage from dINT.
base D = 78+2.
WSC, prior to level correction, 0.2*(63+61) = 24.
Multiplier is 3. 24*0.83 = 19 WSC, using 24*0.84 you get 20 WSC.
85+3*(80+20) = 385, which is what I got. Using 0.83, you would expect 382 damage.
Tried with Magic Hammer too; with 63 MND, got 106 damage on Tiny Mandragora (7 MND), 107 on Bumblebees (6 MND), which would be 1 less on both if level correction was still 0.83.
