Most Numina rely upon the spirits to be in the physical presence of their targets, though the spirit could be somehow hidden or in Twilight. They don’t have to fight fair. Many use the Reaching Numen to attack through the Gauntlet. Any Numen with an (R) after its name can be used with the Reaching Numen.
Anytime a Numen must transcend the Gauntlet to function, the spirit must take the strength of that barrier into consideration. Subtract the dice pool penalty listed in the Gauntlet chart (p. 46). Some Numina depend upon the Reaching Numen to function through the Gauntlet. If this is the case, the Gauntlet modifier only affects the Reaching Numen’s dice pool, not the Numen used via Reaching.
Range can also play a factor, especially with Numen that act similar to guns or mimic other supernatural ranged attacks. For targeted, variable effect ranged attacks such as Blast, assume that short range is equal to the critter’s Power + Finesse times the spirit’s Rank. Medium and long range can then be calculated by multiplying the previous range by two. Targets get the advantage of cover, concealment, defense and armor as normal — though there may be exceptions based upon the specifics of the power. A Rank 2 fire elemental (Power 5 and Finesse 4) with Blast would have these range bands: short 18, medium 36 and long 72 yards.
