[Idea]: Temporary Buffs in Wooden Cases

As the title says, I think it could be kind of interesting if the wooden cases had the small chance to reward players with a Tournament-Like buffs that last for 7 days once acquired.

Buffs would include boosts to basic stats (Attack, Precision, Crit chance, Crit damage, Defense, Dodge, Max HP, Max Hunger, Loot chance, Energy, Entrepreneurship, Productivity) and maybe even buff to movement (temporarily makes max movement points 150 and you regenerate 15/hour)..

The choice of buffs would gravitate towards the dominant build (so that war players don't get eco buffs and vice versa) and would not be stackable (to prevent someone from opening a massive amounts of these and turning into a behemoth).

Lemme know what you think.
