Syntax: cast 'duo dimension'
Cooldown: 25 minutes.
Illusionists are able to lose a dimension and go out of sight, undetectable
by any means, including through true sight. However, duo dimensioned
players can see other duo dimensioned players. This spell protects the
Illusionist from being attacked by aggressive monsters, much like the deter
spell. If an Illusionist flees from a mage mobile, the mobile will track
the player down, cast faerie fog to reveal the player and attack once more.
Duo dimension is not like sneak in that you can enter or exit a room unseen,
but the duo dimension player's name will be concealed.
The duration of the spell depends on the level of the Illusionist. It is
1+(your level/10). The effect is removed once battle begins. Typing
visible or casting the spell again with the effect on will strip the effect.
This is a self‑cast only spell.
