D&D General Why do we color-code Dragons?

[Hriston]

No, but certainly this is perfectly possible.

It's a possibility, yes, but you've been posting as if it's a preordained certainty that characters have no knowledge of dragons whatsoever to justify your accusations that a player who uses information about dragons acquired in gameplay is a filthy metagamer. It's stomach turning how little tolerance you have for even the mention of a play style you yourself don't enjoy.

In any case, I find the whole notion of a playstyle where players memorising monster characteristics is something that is encouraged extremely off putting.

It's not surprising that your preferences are different from those of game designers from 50 years ago. What I find odd is a play style in which the players are expected to ignore the characteristics of the monsters their characters encounter and pretend they didn't notice them. Where's the fun in that?

It's rather interesting to see arguments over something that the Study action was explicitly designed for.

"Can I use the Study action to recall if a troll has any weaknesses?"

"Roll a History check, since trolls are Giants. And since one particular weakness is well known, roll with advantage."

The DM might even assign a low DC for this as well.
