Creatures within a radius of 30 feet per point of Charisma modifier (minimum 30 feet) are subject to the effect if they have fewer Hit Dice than the initiate (dragons are immune to the effect).

以她为中心半径为每魅力加值30尺的范围内(最小半径30尺)的生物，如果生命骰低于龙之传人将会被影响。

By the calculation it is found that the decreasing radius is all the same for different particle radius at per unit time when the spherical sample particle is evaporated.

本文在计算恒温下蒸发球形试样粒子时，发现每单位时间蒸发缩小的半径相等。

It offers 56 megabits per second over a 30-mile radius. (The current standard is 11 megabits per second over a half-mile.) Wi-Max antennas on roofs and water towers will spring up like crazy and may begin to threaten the cable and local telephone empires.
