Ok, so this is less iconic but more of a nod or bow to real-world esotericism and occultism – but an oblique nod to the reality of weapon proficiencies in AD&D as well as trying to define continued and real differences between human and demi-human mages. Now, when we shift back to AD&D from my Home Brew a certain amount of the rules involved in their use get lost – but thier useful nature remains as well as the evocative nature of their presence. Human mages in my campaign world all begin play with a pair of kris.
A mage’s kris are two double-edged daggers, they could be bodice knives, they could be fighting knives, the style depends upon the mage in question. There is a white-handled kris and a black-handled kris, the white is for physical and mundane threats, the black is for spiritual and magical threats. They can be used for offense and defense, in combat or otherwise. each are Dedicated against those threats (the white is treated as Coldsilver Enchanted Blade, the black grants the mage the effects of a Protection vs Evil spell while drawn and held).
This all gives beginning mages a bit more of magical edge than they otherwise have in AD&D, but it isn’t grossly overpowering or out of line with early or low-level magical items. As might be guessed, higher level mages will have kris that are much more elaborate in their magical powers and the kris of powerful mages are rumored to be sentient…
