[General Discussion] Chance of Encounter: 0.0000042%

The veldt is clearly a perfectionist's frustration. You could spend hours upon hours in the WoB trying to fight the right enemy formations and getting all the missable rages, and even then you wouldn't even have half of the game's rages yet. As well, the fights that you can only fight once, have to trigger before the areas become inaccessible, etc. add to the frustration.

I too, in Earthbound, liked the struggle of getting exorbitantly rare Sword of Kings for Poo from a certain monster (Gold Starman?). The smiling sphere or something was a rare enemy in the game that also comes to mind.

My favourite horror story about rare monsters is FFIV's Pink Puffs(1/255?), and the equally rare chance of getting them to drop a certain item (1/255?). That must have caused many completionists much agony to have a mere 1/(255^2) chance at an item, when the monster was rare enough.

While moreso for challenge purposes, it's frustrating to try and encounter hamsters in VP1's Seraphic Gate. You could face them in the room before Iseria Queen, but 90% of the time the monster you ran into gives a battle with a deadly Loki Shade instead of the even deadlier 4 hamsters. That place was dangerous enough to loiter around, housing the most powerful monsters in the game which may even kill you at the highest levels even with Guts + Auto Item.

Jam it back in, in the dark.
