not sure if this is intended. Blood Blade will add more physical modifier each time a physical card is used.
Currently at 700 level, not sure what is the highest level. Also what is the highest level for cards? My highest is God+10.
Another bug I found, if you overheal your Max HP more than a trillion, the next round your Max HP will start at 1.
Tips: Get a few Blood Blade, rush at least two of them to diamond at first, dismantle into any double attack cards. Make sure you have Physical and Siphon activate for 4. Then rush one Blood Blade to God+10.
Could just win like this, but I wanna go for all combo.
