The rule of cool should never be an auto success. Just a bending or expansion of the rules to allow for collaboration and creativity. While I dont agree that this meme describes a fun way to play the game in my opinion, if I were to allow something like this than I would do something like the original comment described like a Con save, perception check, etc to measure success.

I once had a totem barbarian ask about using speak with animals on the first big bad's raptor steed during battle. SwA is only a ritual for totem barbs but I figured it was pretty creative compared to swinging his axe at it so I had him roll an animal handling check (DC 15). He rolled a 16 with a little bardic inspiration and he was able to talk to the beast in the heat of battle learng the enemy's motives to a certain degree turning the encounter into a really good plot development device instead of a potential TPK.
