If the celestial towers are going to be a very,
very high-end High 6-A, then I do believe that the Terrarian and the Moon lord should be baseline 5-C for being superior to them. Or the Terrarian should be 5-C scaling to the moon lord who is superior to them.
Anyhow, like I stated I would, I'll do some of the KE calculations for the Eye of Cthulhu, and then the Destroyer.
As I stated in a previous post and shown in the video,
the Eye of Cthulhu (Near 0:27 or so) can charge about as fast as the meteors from the Meteor Staff. So, instead of scaling how many pixels each one travels in a second in comparison to one another, I'll just say that the Eye of Cthulhu moves at the same speed as said meteors due to charging alongside one falling downwards.
Meteors can travel at speeds ranging from 11,000-72,000 M/S (Which averages out to 41,500 M/S). I will use 11,000 M/S for the low-end, 41,500 M/S for the mid-end, and 72,000 M/S for the high-end. The calculations page also mentions about 17,000 M/S being a decent high-end for them, so I'll include that after the low-end
Now, since the EoC breaks off some of its flesh in its second phase, I will assume it's about 25% hollow (0.75x multiplier for mass).
I calculated its mass (Via square-cube law) in this calculation here - which resulted in
58159.869856 kilograms.
58159.869856 x 0.75 =
43619.9024 Kilograms
Now, all we have to do is plug in the varying velocities in a KE formula for the differing ends.
Low-end
0.5 x 43619.9024 x 11,000^2 =
2639004095200 joules, or
630.7371164435947 Tons of TNT
Multi-City Block level+
Low-high end
0.5 x 43619.9024 x 17,000^2 =
6.3030759e+12 Joules, or
1.50647129541 Kilotons of TNT
Small Town level
Mid-end
0.5 x 43619.9024 x 41,500^2 =
3.75621885e13 Joules, or
8.97757851338 Kilotons of TNT
Town level
High-end
0.5 x 43619.9024 x 72,000^2 =
1.13062787e14 Joules, or
27.0226546367 Kilotons of TNT
Town level
So, the low-end grants us a high-end Tier 8 rating, and the three upper-ends grant us low-end Tier 7 ratings. Likewise, I think the low or low-high ends might be better factoring in the fallen stars - which can fall from the top of the map (Which we are assuming to be the top of the stratosphere - which is 50 kilometers upwards away from Earth - within a few seconds.
Likewise, I can just test on a large world by using a star cannon and shooting a star upwards while flying alongside it to see how long it takes to do so.
Likewise, time for me to do Spazmatism's kinetic energy -
velocity of which is shown near the end of this video.
Spazmatism appears to be moving at an identical pace to the meteors, albeit very slightly slower. For now, I'll just use the velocity ranges of a meteorite as stated above, subject to change.
Spazmatism is a metal version of the Eye of Cthulhu, so I will assume he is made of steel. The density of the human body (Using that for the EoC's density) is 985 kg/m^3, whereas the density of steel is 7,900 kg/m^3
7900 / 985 = 8.02030457x mass difference
8.02030457 x 43619.9024 =
349,844.902562 kilograms
Then I just whap on the velocities in a kinetic energy formula.
Low-end
0.5 x 349,844.902562 x 11,000^2 =

Likewise, I should probably re-do the video for the destroyer where I stand still instead of moving around so I can find the velocity of the destroyer in comparison to the meteors by finding the distance they move in a singular second to one another by comparing to images to one another. The wall of flesh's KE would definitely be higher than that of Spazmatism's due to sheer volume - and the destroyer would be larger in comparison to that, too.
