Robes are stupid. My sorcerer dresses like Petyr Baelish.
To expand: if you are a mage, dress like a noble. Do not dress like a wizard. Pointy conical hat and sky-blue robes is medieval semaphore for “kill first and with extreme prejudice.” Tailored black silk over cloth-of-gold and studded with rubies says “Harmless, but valuable; ransom if possible or kill last.”
If you dress like a noble, they’re not going to pay attention as you take a turn or two to back away from the melee and prepare yourself. The ruse is only broken when you reveal yourself, at which point 8d6 fire damage is screaming toward them at Mach Fuck anyway, so no big.
counterpoint: if you don’t get to dress like someone ran a magical thrift shop through a rototiller and frankensteined the pieces back together what’s the god-damned point of being a wizard
The sartorial differences between wizards and sorcerers are on display, I think.
That makes perfect sense, really, since sorcerers don’t generally get a choice about gaining spellcasting abilities and might not want to advertise them 24/7 whereas wizards put a lot of effort into becoming wizards and didn’t spend years in Wizard Grad School just to be low-key about it.
