dojo dummy was used to measure and compare max dmg hit using battle analysis. video test below not only confirms the bug that tehheavy2 reported but extends to other matt consumables that are not working properly.
00:36 monster park blue potion(30 matt)
00:57 gigajuice(700 matt)
01:33 jigajuice(1000 matt)
01:44 onyx apple (100 matt)
all four buffs used altered visual range but had NO impact to maximum damage(1,211,862,288) throughout ENTIRE test. seemingly only affecting magic attack.
