Bifs & pickaxes suck, to put it mildly
- Bifs have only marginally better coal/iron ore rates than the slimes, and (far) worse rates for other ores;
- Bifs take much longer to whack than slimes, at least at high baselevel;
- Due to slime mothers, slime pits and low abundance of bifs, the "bifs whacked per second" rate is far lower than "slimes whacked per second";
- Pickaxe ore drop boosts look great on paper, but there seems to be another -95% itemchain nerf somewhere, making it not worthwhile to pack a pickaxe and/or bother to switch from main weapon to pickaxe.
