That’s where the low-magic part kicks in. For the most part, weapons are meant to behave as they do in real-life. Sure, they leave out some abilities that the weapon should have for the sake of gameplay (like how the pike should have spearwall, but doesn’t), but they never add abilities that the weapon should not have, nor put in stuff as a regular weapon that never saw any use. There’s Orc weapons, but they still reflect what you’d expect to get in real-life, as in being poorly made and not suitable for human usage variants of existing weapons. Actual fantasy weapons don’t have abilities that they should realistically have, because they never existed, and they’re therefore not included as part of the player’s arsenal. The stranger and more magical is reserved for legendary weapons, so we might see more fantastic items among those.
