GMS Post RED training guide

I really don't agree with the first half of this guide LOL. I get that you're listing options but you never highlight which are the best exp gaining options, and if I didn't know better I would choose the first option on that list to train with (ex: your 30-40 range lists Mushroom Kingdom first. Mushroom Kingdom is not the best exp gainer for 30-40 lol.). And by specifying only the area and not the map I would literally just go to each map with the same level monster as my character, and we all know that's not efficient training.

This is what I do for the early levels. The levels are an estimate depending how impatient I am. Bolded parts highlight the best options if there are multiple options in the level range. References to 2x can be replaced with 3x, 4x, or whatever exp multiplier event there is.

10-15 Blue Ribbon Pigs in Nautilus
15-30 Angry Jellyfish (the map after the Cool Jellyfish in Nautilus)
30-35 CDs in Kerning Square (highest floor)
35-43 Terrace Hall in Ludibrium
43-60 Apparatus Room in Ludibrium
50-60 Dimensional PQ (I'll do this if it's not 2x and I can find a party. If it's 2x I usually go for grinding)
60-100 Monster Park according to level
70-100 Romeo and Juliet PQ (grind the whole way if it's 2x, grind until 5-6 min left on timer for 1x)
70-80 Roids (I would only choose this if I could not find a party and there was 2x going on)
75-140 Monster Park Extreme (this is SO good for a class that has great mobbing skills)
