Almost died today, piglin brutes are no joke.
i was just trying to sneak and steal the netherite upgrade template thing, when 4 of them jumped me, i was on the roof and digging my way down and somehow four of them got in, and i was surrounded, their hits cost 4 hearts even though I'm wearing full diamond. i had 2 totems, i killed one of them, the other one appears and almost kills me, totem number 1 gets used. then the other two attack, i kill one, the other kills me again, totem number 2 gets used. now i have none, a fifth one comes out of nowhere and i was panicking at that point, and i accepted that i was going to lose my hardcore world there, but somehow i managed to kill it. i was panicking and i ran away without getting the upgrade template.
Next time I'll place lava on the top then I'll drink fire resistance and swim down in the lava to the chests.
