Monster Rancher Advance 2 Raising Mechanics

A guide for hidden data and values of Actions and Items and other effects on your monster, transcribed from bedegeln's Speed Run document.

 

Mechanics
US Version Awareness
  • In the first month of a monster's life, be it from shrine or combine, it will gain +45 weight every week until you feed him in the next month. The JP version doesn't behave this way, only EN version.
  • This is why a fresh baby monster will always be Obese and get the Glutton trait if you don't spar immediately, or start at the 4th week of the month.
  • Glutton is automatically acquired when a monster is Obese.

Lifespan and Feeding
A monster's lifespan value varies depending on its main and sub breed, of course. The average lifespan value for this game is 2550. The Lifespan value not simply being "Weeks" allows for smaller than 1 week increments of lifespan adjustments.
MRM's MRA2 Lifespan Values

The Lifespan Value goes down by 10 points every week by default, and drops an additional 5 points if your monster's "Fullness" reaches less than 100 at the start of a week.
(Fullness is a term coined by bedegeln to describe a hidden parameter in the game that has no name)

NOTES:

All these values are added every week. So in the span of a month the monster will gain 4x these values.

The fullness gain value varies just a tiny bit for different monsters.

Notes for reaching Maturity faster:
  • If you take a look at both tables above, you can see why the "Nuts method" works and you can reach maturity faster using it.
  • Feeding nuts just isn't enough to maintain a monster's fullness value above 100, unless you rest every single week.
  • Feeding nothing or dessert will also work here (to accelerate a monster's maturity), but they add or substract too much weight.
  • Once the monster reach "crucial period", banana is the most "balanced" food.

 

Stress and Fatigue
In MRA2, the monster's stress and fatigue values range from 0 to a max of 999.
There are levels for these values, which Holly will tell you. The worse your monster's condition is, the bigger the lifespan hit.

Stress & Fatigue lifespan hits are added on top of the default weekly Lifespan Value of -10 and is additive.
for example if your monster is "Pretty stressed" and "Exhausted" at the start of the week, it will take (10+6+12) = 28 points deducted from its remaining Lifespan Value.

The max Lifespan Value hit is 55 points when your monster is "Really stressed (above 900)", "About to collapse", and its fullness value below 100.

* Holly will still say that your monster is "Really stressed" here, but the lifespan hit is 20 if the value is above 900.

Training
Notes about training:
  • Your monster will be more stressed if it's Slim or Thin, and less stressed if it's Fat and Obese.
  • Your monster will always be more fatigued if it's not at Normal weight.
  • At Fat and Obese fatigue increase is higher.
  • Sparring is not affected by weight.

Great Trainings

The monster will gain -50 stress if you praise it, and +30 stress you don't.

Failed Trainings

There 2 types of failed trainings:
  1. One is when Holly said that your monster "didn't do it right" (failed because of Reliance).
    • Scold it, it will gain 20 more stress, -5 discipline, +1 reliance.
    • Don't scold it, it will gain 20 less stress, +12 discipline, -1 reliance.
  2. The other "didn’t do very well" (because of Discipline, if it's too spoilt the chance for this type will increase).
    • Scold it, it will gain 70 more stress, -12 discipline, +1 reliance.
    • Don't scold it, it will gain 20 less stress, +12 discipline, -1 reliance.
If your monster has the "Expert" trait, the chances for successes and greats are increased (percentage number unknown), but it will gain an additional 60 stress if it fails its training.

Observations:

  • Incense is quite powerful especially for a speedrun.
  • Only the best gem and cup are worth having, though they are quite expensive.
  • The lower-tiered gems and cups reduce too little stress and fatigue to be of any real value.
