CR and how does it work?

[Nickademus]

A goblin can one-shot a 1st-level PC. A hobgoblin working with an ally will almost definitely one-shot a PC.
I suggest you play a little more 5e before trying to make encounters. The monsters are different from previous editions.

Did I understand the DM guide badly, or FG does not apply the multiplier according to the number of monsters?

FG doesn't add a multiplier. It just adds up the XP of all the monsters in the encounter.

The multiplier is for determining encounter difficulty, not for awarding XP. FG's XP tracking is for awarding XP, not for determining encounter difficulty. There is (used to be) an extension that would change this for you, but I haven't heard it mentioned in a long time so it may no longer be supported or work. You can check the stickies to see if it is still listed.

You should also be aware the stuff in the DMG about encounter balancing with number of creatures in't that good after 1st level in my opinion. If you have "Xanther's Guide to Everything" I would use those encounter building instructions. They basically ignore the multiplier.

This is the most workable version of a CR system I've seen: https://theangrygm.com/how-to-f-cr-practical-example-1/
AngryGM gives a way of plotting it out that is very simple and fast. You can use his guidelines for tweaking monsters or creating new ones or just re-scaling existing ones if they are too good or too weak.

Again, it is crazy fast and simple, unlike all the other systems I've seen.

So there is this extension that helps by telling if you made a trivial, medium hard, deadly encounter at the click of a button. It is good to understand how to make encounter and do the math yourself but I found this a big help. It for 5e only I believe.

Hope this helps.

I've made an Excel sheet in the meantime, but this extension is even better

Glad it helped.
