The explains it quite neatly. A game mechanic which makes you use a different type of bullet after a period of time.Just a quick idea I thought of since it was annoying to switch to ichor bullets then to switch back to chlorophyte bullets.An example of what you could do with this mechanic is: Shoot an ichor bullet after 15 seconds (When the ichor debuff effect ends) then switch to another bullet you wish to use. Who else would want this?
