Combat

Nagas favor spells over other forms of combat. Because they are almost always found in the lairs they guard and know well, they can arrange most encounters to suit their wishes.

Dark nagas prefer to fight from an elevated position where they get a good view of the battlefield while also staying out of reach.

Detect Thoughts (Su): A dark naga can continuously detect thoughts as the spell cast by a 9th-level sorcerer (DC 15). This ability is always active.

Poison (Ex): Sting, Fortitude save (DC 16) or lapse into a nightmare-haunted sleep for 2d4 minutes.

Guarded Thoughts (Ex): Dark nagas are immune to any form of mind reading.

Charm Resistance: Dark nagas receive a +2 racial bonus to saving throws against all charm effects (not included in the statistics block).

Spells: Dark nagas cast spells as 7th-level sorcerers.
