I didn't tally mark my runs with n without anzu. I can say though, snatch makes the trash mobs drop silver more, usually they drop 2 silver each more cmmonly with 1-2 stack of snatch on them. As well as Apoc dropping gold chest more frequent with snatch up. Its not a big margin, but given the amount of time you are gonna run events for drops. If u plan to farm a lot, its highly recommended for atleast investing in gran as you can get 3 snatch attempt every 3 turns. Luck is a huge factor definitely, snatch just close that silly margin ever so slightly. N Jelly at all those double anzu users.
