What are the 2 last exotics I'm missing and where do I find them?

You're missing the Spiked Shield and Slime Hammer.
I don't know where the shield is from, but the hammer is from a big slime-cube down in the mines (not dungeon).

Is there a location of this slime?

[obtuse mesa]

The mines are procgen, so it will be different from my game to your game.

Slime is in a bowl like design in the cave, there will be a massive slime cube defending the lightstone box. The shield is on a desert island with another bowl like design full of rolling stone throwers guarding the box. Sounds like you have some exploring to do 😄

Actually, I've explored and almost completed everything. But I may have skipped it since I knew from experience my pickaxe was not strong enough. But it is now and I forgot all about it, thanks!

The spiked shield is found in a desert island where there's a round bowl-like area surrounded with a lot of those Dozers that rolls around and throws rocks before resting
