And now this:
0 defense, 0 astral
Mob hits 85
Mob swings 3 times for 0 DMG, shield breaking hit 20
(3x85)+(85-20)
=
320
1069 defense, 0 astral
Mob hits 73
Mob swings 3 times for 0 DMG, shield breaking hit 17
..now assuming shield doesn't factor defense we continue like this...
(3x85)+(85-17)
=
323
and this:
0 defense, 163 astral
Mob hits 85
Mob swings 7 times for 0 DMG, shield breaking hit 83
(7x85)+(85-83)
=
597
1069 defense, 163 astral
Mob hits 73
Mob swings 7 times for 0 DMG, shield breaking hit 71
(7x85)+(85-71)
=
609
So the numbers don't 'exactly' support shield absorption ignoring defense. How to account for the discrepancy?
