Is this right?

[JmOz]

Character with Find Weakness and Enhanced PER on all senses, can he use his extra PER to act as essentialy Telescopic levels with his Find Weakness?

[Steve Long]

Since Find Weakness has a specific, defined way of buying bonuses to the roll, buy those; Enhanced Perception bonuses do not apply. If the character just wants the bonuses to cancel the Range Modifier, he can apply a -1 Limitation to the purchased bonus.
