Currently when attacking bosses you win a drop i always use 20 stam attack on better xp bosses so is it possible the drops could reflect that so if i attack with 5 stam you have a random chance of 1 drop 10 stam 2 drops 20 stam 3 drops otherwise if i wanna do the boss and have same chance of getting a drop whatever stam attack i use i may as well attack with 1 stam for more drops in total but take very long time to complete the boss
