Thank god for Fizz.

Man I was not going to grind out killing 50 Pepper Rexes for Perfection when I found less than ten on my numerous floor 100 runs.

[Calico Witch]

I seriously considered using Fizz (and had the $$), but I used stairs instead (had those too) to get to the specific floors and it didn't take me more than 3-4 in-game days (can't recall specifically)

I agree with this, I think pepper rex is too troublesome to find because it's quite rare, and to find Prehistoric Floors is pretty hard because it really depends on rng

Just reset the day before sleeping and try again

They're fairly common in hard mode skull cavern not requiring a specific floor layout to spawn.

Pepper Rex is going to be the last eradication goal I finish (only need a few more magma sprites, but 35 or so Pepper Rex), but I'll get them, eventually.

I've been relatively lucky with them; I've never been past floor 51 or so except when I staircased to 100 to complete that quest, but I've come across a few prehistoric floors and also random Pepper Rex on regular floors.

They're tough, but they're also my favourite enemy due to having an awesome name.

The trick is approaching them on the diagonal, they *can* flame diagonally but it takes them a second to swing the attack around toward you. Once they're locked in to that you can spam so many sword strikes.

Yeah, the Rex's were the last for me too and I was somewhat considering not even bothering with the perfection achievement because I read they were formidable (and I'm not fond of combat). But I didn't think they were all that bad. I actually found the magma sprites to be worse.

It's not that they deal too much damage (and if they do, well, I have 100+ cheese on me at all times :D ), but that they take a lot of hits to kill. Fortunately, it's more or less always possible to only fight one of them at a time, even on prehistoric floors.

Magma sprites are way more annoying for sure, especially the pale yellow ones that have the special attack where they stop and then fly at you fast.

Serpents are more annoying than the Rex, too, but easier to hit at the right time than the magma sprites.
