I kinda like this ribbon idea. It's like flag football but the flag prevents you from being instantly fireballed to the face.

I started introducing my kids to tabletop RPGs and this is exactly how we play.

Quick way to end up with Calvin-ball magic. "Oh, but the red ribbon disintegrates if I toot my wooden whistle, making it doubly weak to fire!"

Most times I see "Great D&D ideas" posts are scenarios better suited for any game that's not D&D

This would be great in a more free-form, narrative TTRPG

I feel the same, but tell myself that for many people "DnD" is a stand-in for any sort of imagination game. Like people say "kleenex" for tissue or "xerox" for copy.

This sounds kinda like Mage: The Ascension.

Is the second post included in the screenshot for some reason I'm not getting?

Good fit for Dungeon World.

I think it's a reference to someone entrenched in the FF universe, probably a fan of D&D campaigns, who is being tongue-in-cheek AT'd

This is all expected in the "Powered by the Apocalypse" (PTBA) system and it's spin offs.

There are a few TTRPGs that let you build a magic system for yourself. The most developed one is called Ars Magica. I recently discovered a newer game called Tattered Magicks that also lets you craft magic for your spellcaster.

D&D is fun, but it's not the only rpg out there

So... I take it they're not familiar with Mage?

Exactly.

Hell, there's even Kids On Broomsticks, if you're looking for some Calvinball Lite shenanigans.

Man, I need to play this again at some point

Only round I had the chance of playing was a very short round 15 or so years ago at a convention, where I played a character that basically scripted reality around him with code

Very unconventional, but I'm going to allow it.

Man I forgot all about Dungeon World. I think I backed a kickstarter they did a long time ago. Never got around to playing it tho. I'll have to dig it out and see if my game group is interested.

I spend a Fabula point - do we all agree that red things have resistance against Fire element?

The DM, nodding along fiercely and holding the skull tokens he uses as Ultima points:

Would work pretty well in Fabula Ultima
