This ability is used on a target that has already been afflicted by a -helix spell. When used it substantially increases the damage (appears to be double) and halves the remaining duration.
After a helix spell is cast on a target, a predetermined period of time must elapse before Modus Veritas can be used effectively.
The time delay is low enough to not effect the SCH casting the helix spell, so it's assumed to be 1 regular tick.
Multiple Scholars can stack this effect. It works regardless of who cast the helix (But only one helix can be on any mob at any given time).
It's unclear if the time delay on the helix spell extends to multiple simultanious uses of Modus Veritas. (Ie, does Modus Veritas reset the timer.)
According to a recent update's notes certain Notorious Monsters will demonstrate resistance to the effects of Modus Veritas.
The effect of Modus Veritas can now miss a target completely since the 6/21/10 update.
