1. This spell displaces the image "others see". Is this intentionally formulated this way? Or did you mean this spell displaces the image "others would normally see if they were able to do so"? So does this spell work if it was casted before the target was even near the enemy?Displace Image p. 300 wrote:Illusion. This spell makes a character “invisible” by displacing the image that others see and shifting it a short distance. The magician quickly traces an outline of the target, then touches the “shoulder” of the outline, followed by the shoulder of the target, and makes a Spellcasting test against the target’s Mystic Defense. If successful, an outlined figure shrouded in a shimmering blur appears drifting 4 yards away, quickly transforming into an identical image of the target. The target is no longer visible in his actual location, the illusion having displaced his image.
Attacks made against the image have no effect, and the magician must concentrate to maintain the facade. Each round that the magician does not concentrate gives all attackers a cumulative +5 to Sensing tests against the illusion. Attack tests made against the image count as Sensing tests (see Illusions, p.266).
Success Levels: Increase Duration (+2 rounds)
Extra Threads: Additional Target (+1)
Or if the target was already invisible to begin with (see Notice Not below)?
a. Just noticed now: In the german translation the word "cumulative" is missing. So if I casted this spell and havn't concentrated two rounds on it, the enemies get +10 to the Sensing tests?
b. If I concentrate on the spell in the 3rd round, is the +10 bonus gone and I can stop concentration in the fourth round starting again with a +5 bonus?
3. So the intention to engage in combat is already enough to stop the spell? Or does it only stop after I actually attacked an enemy?Notice Not p. 305 wrote:Illusion. This spell masks a character, making others ignore him entirely. The magician quietly touches the target and makes a Spellcasting test against the target’s Mystic Defense. If successful, anyone in the target’s area will ignore them and subconsciously move out of the way to avoid his presence. If the target interacts with anything in the area, onlookers may make Sensing tests as appropriate. Anyone actively aware (such as guards) may make Perception tests as Sensing tests. Any intention to cause violence will result in the spell ending immediately. This spell explicitly does not protect against any form of astral sensing (e.g. Astral Sight).
Success Levels: Increase Duration (+2 minutes)
Extra Threads: Increase Duration (+2 minutes), Additional Target (+1)
4. Do those two spells work together?
In my opinion I would make the characters and their image created by Displace Self invisible with Notice Not.
After engaging in combat (or after having the intention to do so), the created image will become visible, while the character is still invisbile.
