So far I've gotten some wacky results. The first test where I put not attention I got easily to 20-30 levels. But another test when I seemed to care and put a bit of effort, I went to 130 level, almost with no effort on my paint, just thinking I should get the healing animation and focusing a bit.
Another guy from agdg got to 260 levels and he told me he also seemed to got some wacky combos when he focused, when he was closer to 1 HP.
Would love to see if any anons here can report if some wacky shit happened and if they got diferent results when they focused on the damage or healing spells.
I'm not 100% a real scientist or I can prove a peer reviewed result, but so far this shit seem to be real.
