Pterrorsaurs (Horror)
by LanJaxten
Pterrorsaurs adds Hatzegopterror and Albadraco, two cursed flying pterosaur-style monsters that stalk players, mostly at night.
What it does
Hatzegopterror is described as the last of its kind and more than twice the size of Albadraco. It is a rabid, hard-to-control beast with many scars from past battles, and it stalks prey while waiting for the right moment to attack. Albadraco is a common entity that appears mainly during the night, and it lurks in the darkest parts of the world, usually posing a threat only when it occasionally attacks.
The mod requires Geckolib and runs on both client and server, so the server and every player need it. Files are published for Forge only, for 1.19.2 and 1.20.1, with 1.1.9.2 for 1.20.1 as the latest build, under the Apache License 2.0, which is not open source. The author says it is mainly meant for singleplayer and solo play, and some sounds play between both players in multiplayer.
Key features
Hatzegopterror boss creature
A large flying pterosaur that is too big to melee safely and that flies away about 90 seconds after it stops attacking.
Albadraco night spawns
A common flying entity that appears mainly during the night and stalks players from a distance.
Configurable spawn rates
The mod's config file sets how often Hatzegopterror and Albadraco spawn, and Albadraco spawns can be switched on or off.
Ranged combat approach
Players are advised to bring a long-range weapon such as a bow, trident or crossbow, and to shoot until the entity is hurt.
