Example: a monster called Green Hag Obama would have Green as pre-name, Hag as name and Obama as surname. This separation allows Monstershuffler to pick only the 'name' part when writing descriptions inside the stat block.
When a creature is generic, its name is preceded by the article "the" inside descriptions, like "The hag has advantage on Wisdom (Perc[...]"

You can prevent expressions from increasing ability scores too much by setting a limit here:
Ability scores limit:
A score of 18 is the highest that a person usually reaches. Adventurers can have scores as high as 20, and Monsters and divine beings can have scores as high as 30.
Add an expression for an ability score:
Classes usually make characters increase one ability score by 2 every four levels, which translates into the expression (LVL/4)*2 + 2. You should always add a similar expression to the primary ability score of a class.
Add a saving throw:
If you want to give Expertise (double proficiency) to a saving throw, just add an expression to it with 'PROF' as value.

Calculate the estimated CR of this creature at two different levels (Hit Dice) and write it below. Monstershuffler will then calculate all the other CRs automatically. You can use the instructions at page 274 of the Dungeon Master's Guide or our tables as reference.
Go to the Hit Points settings and set the level (Hit Dice) of the Creature to 1: what is your estimated CR for this creature as a "level 1" monster?
Now set the level (Hit Dice) to the highest number reasonable for this type of creature: what is your estimated CR at that level?
If you want to create monsters or NPCs that can be used consistently from Challenge Rating 0 to Challenge Rating 30, use expressions whenever possible to make statistics dynamic, and enable/disable actions at the appropriate levels!
All monsters and NPCs usually have their proficiency bonus determined by their Challenge Rating. The option "by Level" helps you create Player Character-like creatures when you need one.

You may want to use the expression "8+PROF+ability" for saving throws, where ability is the ability score modifier related to this action (STR DEX CON INT WIS CHA).
Values in "feet"/"-feet" should always be multiplied by 5 because of the way length is measured in D&D battle maps. The length of the fiery breath of a dragon that grows in size every two levels could be written like this"(LVL\2)*5".
This type of value is used inside Multiattack descriptions. It is based on the "Extra attack" feature of the Fighter Class and many melee-type official monsters apparently follow the same rule. These are the results it gives:
Before level 5: one attack
From level 5: two attacks
From level 11: three attacks
From level 20: four attacks
From level 32: five attacks
...giving one extra attack after x levels + 3, where x was the previous interval.

Rust Monster
Iron Scent. The rust monster can pinpoint, by scent, the location of ferrous metal within 30 feet of it.
Rust Metal. Any nonmagical weapon made of metal that hits the rust monster corrodes. After dealing damage, the weapon takes a permanent and cumulative −1 penalty to damage rolls. If its penalty drops to −5, the weapon is destroyed. Nonmagical ammunition made of metal that hits the rust monster is destroyed after dealing damage.
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft, one target. Hit: 5 (1d8 + 1) piercing damage.
Antennae. The rust monster corrodes a nonmagical ferrous metal object it can see within 1 foot of it. If the object isn't being worn or carried, the touch destroys a 1-foot cube of it. If the object is being worn or carried by a creature, the creature can make a DC 11 Dexterity saving throw to avoid the rust monster's touch.
If the object touched is either metal armor or a metal shield being worn or carried, it takes a permanent and cumulative −1 penalty to the AC it offers. Armor reduced to an AC of 10 or a shield that drops to a +0 bonus is destroyed. If the object touched is a held metal weapon, it rusts as described in the Rust Metal trait.
A rust monster was a creature that corroded and ate metal. They were favored by the Mulhorandi god Geb, the dwarven god Abbathor, the gnomish god Flandal Steelskin, and the Duergar gods Laduguer and Deep Duerra.
“Destroyed me hammer and me axe, it did. Put me faith to the test that day, it did.”
— Brawn Thunderstones, dwarf paladin of Dumathoin
Description
A rust monster was the size of a small pony, with four insectlike legs and a squat, humped body. Its hide was thick and lumpy and was yellowish tan on the belly and rust-red on the back. Its tail ended in what looked like a double ended paddle. Two long antennae come out of its head, one under each eye.
Behavior
Normally a docile creature, a rust monster could smell metal from ninety feet away. They always went for the biggest source of metal first, and preferred ferrous metals over precious ones.
Combat
A rust monster had a weak bite and did not normally attack with it. They attacked anyone who had metal, however, with their antennae. The touch of an antenna could turn even magical metal items into rust.
Ecology
Rust monsters ate the rust of freshly rusted metal objects.
Some sages speculated that rust monsters might be related to or the larval form of rust dragons The extremely few rust monsters who lived long enough to reach old age somehow transported themselves to the plane of Acheron, where they ravenously consumed the abundant metal from the plane's cubes for about one year. Afterwards, they encased themselves in cocoons made of spun metal, where they stayed for three years. Following this period, they emerged from their cocoons as rust dragon wyrmlings.
It was not known, however, whether rust monsters were native to Acheron and only traveled to the Prime Material plane as a part of their larval cycle to become rust dragons, or if rust monsters were in fact native to the Prime and were altered by the magic of Acheron once transported there.
Rust monster antennae were used in the creation of rust blades. They found these items extremely delicious and nourishing.
