Rare Spawn Charts

[Infinite Eternity]

Not sure of how much importance this is to people nor how many of these missions actually follow one but should we try to make some?
Notice there are some patterns for some missions as to when a rare spawn appears.
Just got two Guil Shark spawns in a row in Plains Overlord and while the spawns weren't exactly the same I noticed that in the 2nd block both times it lacked the bugs.

For a lot of patterns you won't tell until you're pretty much at the last block anyways.

That aside, here's the easiest way to get them, assuming you have DL missions.

Rappy
Fiery Onslaught - Second room Boomas become Rappy

Guil Shark
MAX 2 Bonus block

Jigo Booma
Max 1 - Rare Pattern if Lutus is the first spawn, Go boomas in bonus become Jigo Booma

Jaggo
MAX 2 Bonus block

Nar Lily
Jungle Charger - No Poison Lily in first room of B2

Delnadian
MAX 3 - Helga route guaranteed

Bil De Melan
MAX 4 - Rare Pattern if Lutus is the first spawn, Grass Assassin (B2) and Kagajibari (B3) becomes Bil De Melan

Darbelan
MAX 3 - Bonus block

Lutus Jigga
MAX 1-4 First enemy

Orgdus
Sleeping Warriors - The B1 door is opened, next spawn is Tavalus and Bajira (which door, I don't know, wiki didn't specify and no one actually cares about Orgy)

Mini Rappy
The Big Push B2- Vorgadyran becomes Mini Rappy
White Beast - B1 2 Olgohmon / 2 Sageeta + B2 4 Olgohmon
White Beast - B1 2 Olgohmon / 2 Sageeta + B2 4 Sageeta

Grinna Bete S
JUMP - Second block guaranteed

YG01U BUGGES
AMF Recovery - B2 first area = 3 AMF Heavy Infantry (worthless, rare is in the next room)
Desert Goliath - B2 first area = No BUGGES or Grinna in first area (also worthless, rare is in the next room)
Train Rescue - Maybe an easier method here.

Sinow Gold
Jump - B2 first spawn

Rappy Igg
Max 1 Bonus block

Seed-Lab Staff
Electronic Brain B3 / Metrolinear B5 - When they pop it's rare!
Bladed Legacy - Maybe an easier method here.
