# Phases
A "**phase**" decribes how the effect varies between letters.
You can modify an effect phase either through the inspector, or via rich text tags [modifiers](/text-animator-unity/effects/how-to-edit-effects/modifiers.md).
Example for rich text tags:
* Make an effect twice as fast: "\s=2>"
* Modify offsets: "\i=.1 w=.3>" (will set char offset as 0.1, and word as 0.3)
### Extra notes about offsets
* An offset of 0 or of 1 means that the effect is the same on all character
* If you go from 0 to 0.5, the effect is shifted in one direction, while from 1 to 0.5 is shifted in the opposite direction (where 0.5 is higher)
* An offset of 0.5 means that one character is in one direction, and another is in the opposite one
