Welcome to my short guide to add new nicknames to the framework.

Needed files: your_amazing_mod common nicknames your_amazing_mod_nicknames.txt on_action your_amazing_mod_on_action.txt events your_amazing_mod_events.txt localization your_amazing_mod_l_english.yml (your_amazing_mod_l_french.yml, etc.)

In CK2, the nicknames file were where the magic happened. In CK3, it's merely a place to declare that the nickname exists. Your nicknames file should look like this:

nick_my_amazing_nickname = { is_bad = yes/no #Whether it's bad or good, default to no is_prefix = yes/no #Whether it's a prefix, default to no } nick_my_wonderful_nickname = {} # You can leave out unnecessary statements ...

The on_action file should be fairly simple too. It just ties the events which will give your nicknames to the random selection.

nickname_selection = { # You must use this name random_events = { 100 = my_amazing_namespace.0001 100 = my_amazing_namespace.0002 ... } }

Then comes the event file. First you declare a new namespace for your events. After that, you list the events which will give your nicknames when chosen by the random selection.

namespace = my_amazing_namespace

my_amazing_namespace.0001 = { hidden = yes trigger = { # Conditions to get the nickname. age >= 20 has_trait = diligent has_trait = ambitious } weight_multiplier = { # Weight to get the nickname. The higher the value, the more likely a character will get it. base = 1 modifier = { factor = 2 has_trait = calm } }

immediate = {
	set_nickname_effect = { NICKNAME = nick_my_amazing_nickname }
}

} my_amazing_namespace.0002 = { ... } ...

Lastly, the localization files. They are just the English, French, etc. text displayed for the nickname.

l_english/l_french/...: nick_my_amazing_nickname:0 "the Amazing" nick_my_wonderful_nickname:0 "the Wonderful"

And that's it! Run you mod and enjoy!
