oh i didnt even notice the -5 stamina drop, but now i see there is a trinket to equip that negates that (gilded shift). But 100/100 to 95/115 doesnt bother me too much. I usually go for the green stamina boots all the time anyways.
Similar bonuses are a concern; maybe allow player to set up the auto switching order based on items of their chose. and have a new upgrade that gives you more auto switching slots. like maybe start with 2: player puts copper then iron pickaxe then after another upgrade then they put a drill in etc…
