Decaying Edge

This spell is a part of the Deconstruction spell chain and is found in the Deconstruction rune stone.

The seniumancer has by now spent enough time in the company of The Worm to understand something that most people never will; decay is not an event. It is a process. It does not arrive and then leave. It begins, and then it continues, each stage feeding into the next, each moment of rot opening the way for deeper rot still. It does not rush. It does not need to. Time and entropy are always on its side. When the seniumancer casts Decaying Edge they are giving the weapon enchanted the ability bring the truth of decay and entropy to the foes that feel its impact. 

When this spell is cast, the seniumancer reaches into the deepest parts of their runic soul, seeking the darkest symbol of their affinity, The Worm. Once found they make their pact and draw The Worm's hunger into the weapon; be it blade, fist, bow, or whatever instrument of harm the target carries. The weapon does not change in appearance, not obviously. There is perhaps a faint wrongness to it, a slight discoloration at the edge, the ghost of something unpleasant. But the first time it strikes a living target the truth of what has been done becomes impossible to ignore.

The damage the weapon deals does not simply wound the body. It feeds. Every point of damage inflicted is simultaneously drawn from the target's Soul and Power as the decay reaches past the flesh and into the reserves that keep a person standing and fighting. And with each successful hit, the rot takes hold a little deeper as the target begins to lose 1% of their remaining Vitality with every passing round. The wound does not close but continues to work inward long after the blade has moved on. Each additional hit compounds this, the decay accelerating as The Worm grows more confident that this particular feast will not be interrupted. The seniumancer watches this with the same quiet detachment they bring to everything. They did not invent entropy. They simply gave it an edge.
