Ti-khana Creature
A twisted result of yuan-ti experimentation and cross-breeding, a ti-khana creature is a psionic hybrid of reptilian animal or magical beast and yuan-ti qualities.
Creating A Ti-khana
"Ti-khana" is a template that can be applied to any lizard, dinosaur, snake, or any animal or magical beast that is reptilian. The creature's type becomes magical beast. It uses all the base creature's statistics and abilities except as noted here.
AC: Natural armor improves by +4.
Attacks: As a magical beast, a ti-khana creature has a base attack bonus equal to its Hit Dice. If the base creature does not have a bite attack, the ti-khana creature gains one.
Damage: A ti-khana creature's bite attack deals damage as shown on the table below, or as the base creature, whichever is better. In addition to the damage, a ti-khana's bite injects venom.
| Ti-Khana Size | Bite Damage |
| Fine | 1 |
| Diminutive | 1d2 |
| Tiny | 1d3 |
| Small | 1d4 |
| Medium-size | 1d6 |
| Large | 2d4 |
| Huge | 2d6 |
| Gargantuan | 2d8 |
| Colossal | 4d6 |
Special Attacks: A ti-khana creature gains all the following special attacks:
Poison (Ex): A ti-khana creature delivers its poison (Fort DC 10 + 1/2 creature's HD - creature's Con modifier negates) with each successful bite attack. Initial and secondary damage are the same (1d6 Con).
Psionics (Sp): A ti-khana creature can produce the following effects at will.
Detect Poison: As the spell cast by a 6th-level sorcerer.
Alternate Form: A ti-khana creature can assume the form of a Tiny to Large viper (see the Monster Manual). The ti-khana creature uses its own or the viper's poison, whichever it prefers.
Aversion: A ti-khana creature creates a compulsion effect targeting one creature within 30 feet. The subject must succeed on a Will save (DC 17) or gain an aversion to snakes for 10 minutes. Affected subjects must stay at least 20 feet from any snake, yuan-ti, or ti-khana, alive or dead; if already within 20 feet, they move away. A subject can overcome the compulsion by making another Will save (DC 17), but still suffers from deep anxiety. This anxiety causes a -4 penalty to Dexterity until the effect wears off or the subject is no longer within 20 feet of a snake, yuan-ti, on ti-khana. This ability is otherwise similar to antipathy as cast by a 16th-level sorcerer.
When a yuan-ti uses this ability, the aversion applies to ti-khana creatures as well as snakes and yuan-ti.
Special Qualities: A ti-khana has spell resistance equal to 13 + the base creature's Challenge Rating.
Abilities: A ti-khana creature's Dexterity and Intelligence both increase by +2.
Skills: A ti-khana creature has normal skill points for a magical beast of its Hit Dice and Intelligence ([2 + Int modifier] x [HD + 3]).
Climate/Terrain: Warm forest and underground.
Challenge Rating: Same as the base creature +2.
Alignment: Always chaotic evil.
Level Adjustment: +4.
Sample Ti-khana Creature: Ti-Khana Deinonychus.
