===DE Drop Behaviors===

DE drops is a complicated mechanic. To farm for them efficiently, you need to know how their drop mechanic really works. For full details of how it works, you can check out these articles [https://note.com/shiroos/n/nc69eeb09585f], [https://note.com/shiroos/n/nf94178915b6c]. But here is the TLDR version:

====How DE drop works====

DE drops in 7-4 is a complicated mechanic. To farm for them efficiently, you need to know how their drop mechanic really works. For full details of how it works, you can check out these articles [https://note.com/shiroos/n/nc69eeb09585f], [https://note.com/shiroos/n/nf94178915b6c]. But here is the TLDR version:

*If you own '''3 copies''' of a DE and start farming for her 4th copy onwards, her drop rate will be decreased (This is known as '''possession penalty'''). So try to '''keep 2 copies''' of each DE at best.

*For every time that DE is '''scrapped, sunk or fed away using modernization''', the game will add '''+1''' to your '''cumulative decommission''' counter for that DE. If this counter '''reaches 10 or more''', the rate of that DE drop will also be decreased (This is known as '''cumulative penalty'''). Keep this in mind if you fed away too many of that DE.

**The '''cumulative penalty''' starts taking real effect and reduce the DE drop rate also depends on which sea area you are farming. For spring event 2024 E2 Boss, the effect starts kicking in when the '''cumulative decommission''' counter is '''14 or higher''' [https://x.com/shiroos/status/1772304298669457604], for map 1-3, it kicks in when the counter is '''10 or higher''' [https://x.com/shiroos/status/1728817901686452653]. There is no fixed amount for this counter as it can change, so the safest bet is still try to keep the counter at '''9 or less''' to avoid the penalty.

**Lastly, when '''cumulative penalty''' kicks in, it '''doesn't reduce that DE drop rate to 0%''', it's just really low rate, so it's still possible to farm for her, just very unlikely.
