Signet of Illusions

Signet of Illusions is an elite skill mentioned in the Guild Wars Nightfall Prerelease Bonus Pack booklet and on the official Nightfall skill preview page:


 * ''"Activating the new mesmer skill Signet of Illusions allows you to use your Illusion Magic attribute on the next spell you cast.


 * "Many of the "steal spell" style skills, like Arcane Thievery or the Inspire/Reveals, felt like they couldn't be fully utilized in their current form. We decided to give the Mesmer Signet of Illusions, which will make the next spell you cast use your Illusion attribute instead of its normal attribute."

Usage Notes
The next spell you cast uses your attribute rank in Illusion Magic as opposed to its actual linked attribute. For characters investing in Illusion Magic, it may be worthwhile to spend a skill slot rather than attribute points to power a non-Illusion Magic skill or useful in combination with skills such as Inspired Hex, Inspired Enchantment, and Arcane Thievery.

You will also find this being an opening to many new builds where skills which would normally require an attribute spread can be cast without doing so, allowing for the old compromise between versatility and potency to be somewhat reduced. This will obviously extend to the use of this signet for spells which would otherwise not be worthwhile for a mesmer due to its being linked to a primary attribute (such as a build where a mesmer utilizes Spellbreaker to assist allies, or themselves). This is obviously, however, speculation.
