Premise[]
The Penitent One crumbles this statue in two swings. Not bad. Requested by ArbitraryNumbers.
Calc[]

Penitent One = 73 px = 171 cm
Statue Arm = 140 px =
Aight, so this arm is 327.95 cm, and the arm tends to be about 33.3% of total height, meaning our statue here should be about 983.84 cm tall. That's 5.75x larger than an average human.
So if he's 5.75x taller than 171 cm.
5.75^3 = 190.11 larger overall. If a normal human has 0.0711 m^3 as their volume, this guy has 13.52 m^3 of volume, which I will assume is partially stone (33% seems fair).
Volume of Stone = 9.06 m^3
We'll assume V. Frag and Pulv since first it crumbles but then it literally can't be seen anymore.
V. Frag = 69 j/cc * 9060000 cc = 6.251e8 Joules, Small Building level+
Pulv = 214 j/cc * 9060000 cc = 1.939e9 Joules, Building level
Divide by two to account for two hits taken to do this.
