Item
Hunting Trophy is an in-game item that can be bought from a Shop or can be found in a Crate. Most Items modify the Stats of the player, and some of them provide additional effects.
Stacking
When an enemy is killed with critical hit, for each Hunting Trophy the character has, the game rolls a 33% chance to drop 1 material. If there are 2 hunting trophies, it rolls twice. If there are 10, it rolls the 33% chance 10 times.
If there are 2 Hunting trophies, it can drop 2 coins with 1/9 chance, it can drop 1 coin with 4/9 chance, and not drop any with 4/9 chance.
If there are 3, it could drop 0 to 3 coins depending on chances.
