Very stupid question, there's not a way to increase the drop rate of items and summons right?
Haven't checked how it actually works but I think it's impossible because my guess the flow is (sorry if it's a bit technical):
1. Hit the enemies
2. Client (fgo on our phone) will calculate the damage
3. Call fgo server with the total damage and/or remaining enemies HP
4. If the enemy dead, fgo server will decide what drops will be given
What BMT does in "quick win" and "damage multiplication" feature is to somehow modify the point 2, whereas in "1 turn win" is to bypass the point 2 and 3 hence we don't get the drops.
In short: it's impossible because the server that decides the drops and BMT as the client has no power/access to modify it
Correct me if I'm wrong, I'm really love what BMT do
