Spell Effect Text

When a unit is being affected by a spell, ie. Inner Fire, Frost Armor, Heal, etc. there is a mini icon that appears underneath the character's name and stats describing the effect:

Frost Armor

This unit is under the effect of Frost Armor and has it's armor increased. Units attacking this unit will have their movement speed slowed.

Does anyone know how to change the icon and the text that appears here?

Yes, that is the buff art. All you need to do is to edit the .txt file's spell specific buffart. These .txt files are in war3patch.mpq and war3x.mpq under "Units\<Racename>abiltyfunc.txt" and "Units\<Racename>abilitystrings.txt". For example if you wanted to change frost armor get out the Units\UndeadAbilityStrings.txt and Units\UndeadAbilityFunc.txt, edit it as you like.

Is there any other way of doing it? Changing the mpq files is fine for when I play, but other people won't be able to alter their's. I know Tides of Blood did this somehow and saved it into the map. Does anyone know how they did it?

Edit the files from the MPQ, and import it into the map file. If you don't have Frozen Throne, you'll need to use an MPQ editor to insert the files into the map...which I won't go into here.

When you import them into your map, remember to use the right directory, ex. undeadabilityfunc.txt would be imported as "Units\undeadabilityfunc.txt" without the quotes.

I've got Frozen Throne and I've been able to edit the abilityfunc.txt, but I can't find the strings.txt files for any of the races with my MPQ viewer. Can you tell me exactly how they're spelled so I can extract them?

My MPQ editor loads 0 out of 132 files in war3patch.mpq???
Hmmm, they don't seem to be in war3x.mpq, check war3patch, I know that has 4 out of 5 of them (can't find the human one)

Found it! It's in the local mpq file, not the regular one. Thanks for your help.
