there are 2 type of sequence in bronze chest / silver chest / gold chest
the first one is name of item list as you see in the table (box)
the second one is order of drop list as you see in the first picture Lutrus posted above.
1/ you open a few bronze chest, like maybe 10 bronze chest
let say you get: com(1 heal) com(1 heal) rare(5 heal) com(1 base boost) rare(5 base boost)
2/ find in name of item where these item stand next to each other in common table: 1 heal 1 heal 1 base boost
and rare table: 5 heal and 5 base boost
find in order list the part show com com rare com rare
3/ repeat the steps until you see how it works.
same for silver: if you see rareM, you search in rare monument table
