EmAySee Random String Selector (20)

A twenty-slot prompt roulette. You paste up to twenty different strings - subject variations, style swaps, negative-prompt candidates - and the node picks one at random for each run and hands it to your CLIP encoder. It's the heavyweight of the pack's string-selector family, and the one you want when "random prompt" means a real pool, not a coin flip between two.

How it works

Every input is optional: string_1 through string_20. Leave any slot empty and it's simply not in the pool - so you can start with four filled and grow to twenty without reconfiguring anything. A seed input controls the pick, so the same seed + same pool gives the same winner, which is handy when you want to reproduce an exact run.

Output is selected_string (STRING), a single string you wire into a CLIP Text Encode (or a text combine, or a filename template - wherever a string goes).

The seed nuance

The seed widget is required, and it does gate the selection - this isn't the "every run is new" roulette you get elsewhere in this pack. Set the seed and randomize it on the widget to get a fresh pick per run; leave it fixed and you'll get the same slot forever. That trips people up in the other direction: they expect randomness and get the same string five runs in a row because the seed never changed. ComfyUI's "randomize" button on the widget fixes it in one click.

Where it fits

This is the classic "wildcard without a wildcard file" pattern. Instead of maintaining a wildcard text file and a wildcard processor, you type your variations directly into the node. Fewer moving parts, and you can see the whole pool on screen at once. The trade-off is 20 hard-coded slots - for a truly enormous pool you'd still want a real wildcard system, and this pack's other pickers are better when you only need 2–4 options.
