On the Subject of 100 Levels of Defusal

Θ(n) wooo!

Solve modules until unlock. Progress bar :D

1. Find all of the shown letters in the grid below and denote their coordinates as (row, column) pairs only using the unfilled cells.
2. 
   

   $A$ = 1/2 (sum(rowvalues)^2 - sum(squares of rowvalues))     
   $B$ = 1/2 (sum(colvalues)^2 - sum(squares of colvalues))     

3. Sum $A$ and $B$ and multiply by the level number, if you’re not playing 100 LoD multiply by 15 instead.
4. Convert it to base 6 and replace all 0s with 6s, then prepend with 0s until you have one more digit than the display length.
5. For each pair, from left to right, enter the letter at that position in the table below.

	0	1	2	3	4	5	6
0	A	A	E	E	I	O	U
1	A	B	C	D	F	G	H
2	E	C	J	K	L	M	N
3	E	D	K	P	Q	R	S
4	I	F	L	Q	T	V	W
5	O	G	M	R	V	X	Y
6	U	H	N	S	W	Y	Z
