They were left behind many versions ago, in a more primitive Dragon mod ... but they're back now!
Adds a basilisk to the game. Advanced tameability, textures included for caravan packs, valuable leather, etc.
Will appear - rarely - in the following biomes:
Temperate Forest
Tropical Rainforest
Arid Shrubland
Temperate Swamp
Tropical Swamp
Desert
Grasslands
Scarlands
Lava Fields
Glowforest
If you use Vanilla Expanded Framework, a basilisk acid spit attack is added. Fun times!
Thanks to Wagwansugar and Broken Valkyrie (old Dragon mod) and GreyFluffs and Tammabanana (whom I believe created the textures)
