[Talking about the hermetic version of the rune magic]
"Every spell that uses the Rune Duration and the Inscription Target is considered a powerful mystical effect, which always gives the target a Warping Point. There is no way to design a rune spell not to Warp a particular target as with other Hermetic spells. That weakness explain why rune wizards are said to have become Warped much more quickly than Hermetic magi, and traditionally guarded their runes very closely, destroying them after they had served their purpose."

[Talking about the original version of the rune magic]
"Rune magic still causes Warping to a target over time, even though its effects seem natural, as a consequence of being exposed to a constant magical effect. The target also experiences Warping from rune spells of Level 30 or greater, unless the vitki casts the effect on himself."
Both the original and the hermetic version of the rune magic are identical (beside the "translation" from 24 runes to 15 arts), but this part is not.
Are vitki (non Hermetic rune wizards) so much more Warped then Hermetic magi or not?
