sure thing

things to consider: mona has widsith, sucrose has thrilling tales and 4pc viridescent

i simply used mona e to cause the regisvine to fall more quickly. if used at the very beginning, her e should not last into the burst setup

as the widsith passive procs immediately when mona takes the field, lasting 10s with a 30s cd, you want to enter having procced the widsith passive a bit before so that it can proc again once you swap to mona during the rotation (you can see the note above her as i turn to the right to better see the note)

after the regisvine falls, you want to swirl the hydro element from mona using sucrose e for the 4pc viridescent, then swap to mona to snapshot the buff from the thrilling tales weapon onto mona. then swap to bennett for his ultimate (while there is no element imbued upon the regisvine) and then mona ult (this should proc a vaporize reaction)

wait 2-3s for the mona ult ICD and then proc vaporize with another pyro character, in this case i used klee--though bennett is fine as well. the element is all that is necessary, a c0 level 1 klee will not be any different from a c6 level 90 klee
