Magic-Psionic Transparency

Though not explicitly called out in the spell descriptions or magic item descriptions, spells, spell-like abilities, and magic items that could potentially affect psionics do affect psionics. When the rule about psionics–magic transparency is in effect, it has the following ramifications.

Spell resistance is effective against powers, using the same mechanics. Likewise, power resistance is effective against spells, using the same mechanics as spell resistance. If a creature has one kind of resistance, it is assumed to have the other. (The effects have similar ends despite having been brought about by different means.)

All spells that dispel magic have equal effect against powers of the same level using the same mechanics, and vice versa.

The spell detect magic detects powers, their number, and their strength and location within 3 rounds (though a Spellcraft check is necessary to identify the discipline of the psionic aura), while detect psionics detects spells, their number, and their strength and location within 3 rounds (though a Spellcraft check is necessary to identify the school of magic).

Dead magic areas are also dead psionics areas.

Unless specifically mentioned in a power’s description, a power cannot be counterspelled when it is being manifested, nor can powers be used to counterspell a spell as it is being cast. Unless specifically stated otherwise, feats such as metamagic feats that specifically affect spells do not affect powers, and feats such as metapsionic feats that specifically affect powers do not affect spells.

Powers or psionic effects usually work as described no matter how many other powers, psionic effects, spells, or magical effects happen to be operating in the same area or on the same recipient. Except in special cases, a power does not affect the way another power or spell operates. Whenever a power has a specific effect on other powers or spells, the power description explains the effect (and vice versa for spells that affect powers). Several other general rules apply when powers, spells, magical effects, or psionic effects operate in the same place. powers that provide bonuses or penalties on attack rolls, damage rolls, saving throws, and other attributes usually do not stack with themselves. More generally, two bonuses of the same type don’t stack even if they come from different powers, or one from a power and one from a spell. You use whichever bonus gives you the better result.
