1 The caster’s level applies to adjusted difficulty before any other modifiers for material components and conditions.
2 Specialist wizards receive this modifier when casting true dweomers that use a type of spell from their schools of specialization.
3 This adjustment only applies if the spell is cast the same way it was previously. If range, duration, or other attributes are changed, the –10 reduction does not apply.
4 If the true dweomer normally allows a saving throw, the caster can alter the spell’s adjusted difficulty to increase or decrease the target’s saving throw as explained below (see the True Dweomers in Play section for more information).
Each +5 added to the difficulty imposes a –1 saving throw modifier on the target; each –5 subtracted from the difficulty gives the target a +1 saving throw bonus. A difficulty modifier of 100 eliminates any saving throw.
A true dweomer’s adjusted difficulty can be increased to reduce the target’s magic resistance, including resistance provided by a ward spell. Each +1 added to the difficulty reduces magic resistance by –1. It is not possible to reduce a spell’s difficulty by increasing the target’s magic resistance. If the resistance penalty lowers the target’s magic resistance to 0 or less, there is no further effect other than negating the roll.
