find your char lvl on other axis
where the row/column meet is the result ilvl after 1 roll
repeat process for # of rolls
e.g. starting with a lvl 99 char and lvl 99 item
ilvl99 -> ilvl 78 -> ilvl70 -> ilvl67 -> ilvl65 -> ilvl65
if your char is lvl 95 youll bottom out at 62
you can also use the chart to find target char lvl to roll certain ilvls etc
