Random D100 Pellucidar & Pres-historic Inner Earth Encounters Tables For Amazing Adventures Rpg By Troll Lord Games

 Here is a d100 Dinosaur and Prehistoric Creature Encounter Table specifically designed for Troll Lord Games’ Amazing Adventures RPG (the SIEGE Engine multi-genre pulp system). This picks up from 

A Comprehensive d100 Hex-Crawl Lost City & Lost Peoples Generator formatted for Troll Lord Games Amazing Adventures RPG (Siege Engine system)

This table incorporates standard SIEGE Engine mechanics—such as Physical (P) or Mental (M) Saves, Hit Dice (HD), and SIEGE Attribute Checks—blending Apex Theropods, Sauropods, Ceratopsians, Marine Reptiles, Pterosaurs, and Cenozoic Megafauna into a high-pulp exploration tool.

Running Dinosaurs in SIEGE Engine

In Amazing Adventures, non-combat actions or saving throws against special creature attacks use a SIEGE Check:

• Primary Attribute Check: Challenge Base (CB) 12 + Challenge Level (CL = creature Hit Dice or situational penalty).

• Secondary Attribute Check: Challenge Base (CB) 18 + CL.

• Saves: Monsters specify P (Physical: STR, DEX, CON) or M (Mental: INT, WIS, CHA) for saving throw bonuses.
