Arcane Shield isn't working properly

[frankexs]

500/0.3=1667 without any upgrade

means I can take 1667 "original" total damage before the shield breaks

Edit: I should take 1667*0.7=1167dmg while the shield absorbs 500dmg



but it break right after I took 2 hits from an elite goblin

each hit causes around 260dmg (260*2=520, much lesser than 1667)

520*(0.3/0.7)=223

means the shield without any upgrade only absorbs 223dmg before it breaks

it should be 500 but not 223
