Psionics

Not to be confused with psychic magic.

As stated in the rules section, there is semi-transparency between psionics and magic.

Semi-Transparency

In a game of semi-transparency, psionics and magic interact to an extent, but are treated as moderately different.

• Power resistance works against magic, but is reduced by 10 (so PR 17 becomes SR 7).
• Spell resistance works against psionics, but is reduced by 10 (so SR 17 becomes PR 7).
• Dispel magic takes a -10 penalty to its rolls against psionic effects.
• Dispel psionics takes a -10 penalty to its rolls against magical effects.
• Anti-magic fields / dead magic zones have a 50% chance of affecting a psionic item or effect.
• Null psionics fields have a 50% chance of affecting a magical item or effect.
• Detect magic does not detect psionics.
• Detect psionics does not detect magic.

Other cases

• UMD and DR/magic treats psionics as magic, as there are no equivalent alternatives.

Practitioners

Among the playable races, psionics are performed exclusively by Elans, a restricted race. It is available, and you're welcome to use it, but it may comes with some baggage. Talk with the DM if you want to give it a go, and you will get some further details.
