Roll d20 to select an entry; then determine the number encountered from its listed range. The d20 notation follows the source’s 1–20 Die Roll column.
These are Basic D&D reference tables, not a newly assigned encounter schedule for the Caves. Original alignment abbreviations and special markers are retained; no new special-marker mechanics are supplied.
The supplied PDF has overlapping type and die-roll labels around entries 3–5 and 18–20. Roll indices here follow the twenty entries in order. The Doppleganger and Driver Ant number cells overlap (visible 2–8 and 1–6); their individual counts remain unresolved rather than guessed.

Source: B2, PDF page(s) 19. Original narrative retained where present.
