An amazing artefact, made by sorcerers of the world of the shadows to strengthen shadow warriors.
When used it places a rune seal on your Shadow, which increases its Initiative by 5 units. This artefact cannot be used if your Shadow already has 5 or more Initiative seals. Note: you can place 1 seal of each type on a Shadow for each of its levels from level 7 and above (so a level 7 shadow can have one seal of each type, a level 8 can have two of each type, level 9 can have three and so on).
The magic of the artefact is sufficient for 1 use.
