The way to think about the general framework here is that, it is writing the whole map at once. Your creatures are being injected into that. The rarity function and the level function give you control over the distribution of monsters in the level, and all levels surrounding that level (in the same branch), simultaneously.

What you want to imagine is that, if you increase the rarity, you increase the size of the entire distribution curve over the level you specify in the level function:

Suppose the distribution (independent of other creatures), looks like the red curve – that is, the curve maps out that monster's chance to get placed, if it is considered for placement, on some position in some banch, with the left side being the early levels of the branch, and the right side being the deep levels.

If you increase the level return val for a creature, it moves the central axis for the curve for that monster deeper into the branch. If you increase the rarity return val for a creature, you get a larger curve. it doesnt sharpen (become like the blue curve), it doesnt change shape.

you probably want to do that. You want

• sharp curves – for monsters that should more or less only spawn around a specific level.
• soft curves – for monsters that are fairly rare, so the don't only show up basically on the one level from the level function. (the natural distribution is several levels wide, and should be regarded as a wide distribution imho)
• asymetrical curves, with a sharp curve before the level you target – so the monster basically doesnt show up too early, but comes on in force once you get to that level
• sharp curve after the target level – so that another creature that shows up later in enum.h doesnt lose slots to a high-frequency creature with a slightly smaller level func ret val for this creature.

Here's how to do that in your custom rarity function:

int mons_MYBRANCH_rare(int mcls)
{
	int rarity;
	int sharp_before; // cutoff applied on levels shallower by <= than
	int soft_until;   // cutoff artificially applied on levels deeper by >= than
	bool sharp_curve = false;
	bool soft_curve  = false;

    switch (mcls)
    {
    case MONS_WITH_SOFT_UNTIL:
	soft_until = 1;
    case MONS_WITH_NORMAL_ASYM_CURVE: // high-frequency monsters benefit more from a sharpbefore/soft-after curve
    	rarity = 205;
		break;
    case MONS_WITH_SYMMETRIC_SHARP: // this monster would lose slots to NORMAL_ASYM if a few levels above it,
        rarity = 105;               // but not to SOFT_UNTIL if it was at the same place.
                break;
    case MONS_WITH_SHARP_BEFORE:  // this monster has an inflated distribution before the target level, and on the
	sharp_before = 2;         // level above that, but it reverts to a noraml sharp distribution further up.
    	rarity = 40;
		break;
    case MONS_WITH_SYMMETRIC_SOFT: // rarer creatures benefit more from a soft curve
        soft_curve = true;
        rarity = 30;
                break;
      default:
        return 0;
    }
    
    if (soft_curve)
        return rarity;

    const int mlev = mons_dwarf_level(mcls);
    const int diff = mlev - you.absdepth0;
    if ( ((diff > soft_until) or ((diff < 0) and (abs(diff) > sharp_before)) and
            ((soft_until > 0) or (sharp_before > 0))) or (diff >= 0) )
        sharp_curve = true; // its a shadow-reuse, sorry :( 

     // by default, this section makes rarity much higher for placing monsters 
     // above their level
    if (sharp_curve)
    { // fake integer sqroot
        int i=0;
        while( (i*i) <= rarity )
        {
         i+=1;
        } 
        rarity = i;
    }

    return rarity;
}

Obviously you can tune the specific decrease, should you want to do that. For most purposes, this aught to suffice.

The code uses two functions, a level function and a rarity function both functions are allowed to (but neednt) take into account the current level the player is on (or anything in the you object, in fact). The formula looks something like this:

• limit = abs( actual_level - level_func(monster) )
• limit *= limit /* limit is squared */
• chance = rarity_func(monster) - limit
• if random(100) < chance /* generate the monster */

It loops through every grid-cel on the map, and decides if a thing can be placed, and gives a small chance of placing a creature, selected by that frequency formula (odds are such that on most autogenerated maps around 25 monsters will be placed). It loops through all monsters for each placement, regardless of their likelhood – even though the bulk of all monsters will never be placed. It does this in a specific order, I think, and this means that a highly likely creature will steal slots from another highly likely creature if it is earlier in the list.

If it finds no monster that beat the odds of that last step in the fromula, it then relaxes the limit .. this introduces the chance to get any monster (tuning this can be done by not setting the default return val for the level func to an absurd level. Don't forget to add monsters deeper than the max depth for the branch, for OOD monster generation!

my crawlrc – IMHO mostly nice for its monster glyph replacements
