Oil of Balance

Description
Prepared by a secret process, known only to those slaves of the Giant-kings who toiled in the arena, oils such as these were used to subtly influence the outcomes of arena combat. This oil, when coating a weapon, seems to ease the passage of the weapon through the air. Blades cut more easily, and maces seem to leap forward of their own volition. The downside is that the oil is acidic and eats away at the weapon over time, rendering it brittle and much more likely to break.
