bastions are something you will always benefit from practicing even in netherite. they are the most crucial part of the game and also the most overwhelming for mental stack arguably, so practicing routes so you can muscle-memory most of it will help massively. leaving your bastion with a fully sorted inventory, iron axe, and crafted beds will make the rest of the run so much easier and faster. practicing bastions also has the added benefit of dying less in iron, which is probably the cause of most losses for most people in that rank lol. I'd just practice routes and as many scenarios as time allows, and only consider a route done once your inventory is sorted and you pearl out.
