Neutral bombs were dealing damage in the web trial and full versions ver. 1.00 and ver. 1.01 of Immaterial and Missing Power. Since ver. 1.02 the N-bombs do not deal any damage.
Defensive bombs were also dealing damage in the web trial and full versions ver. 1.00 and ver. 1.01 of Immaterial and Missing Power, although less than the N-bombs.
Also, in the web trial and full version ver. 1.00, the spirit bar was regenerating upon using the D-bomb. In later versions the spirit bar remains unaffected. Since ver. 1.02 the D-bombs do not deal damage anymore either.
Many thanks to @roamerb for teaching me how to consistently trigger the defensive bomb.
