Skeletons receive some minimal boosts relative to character level.

Player-character level lower than 4: Skeletons have half HP, no bonus cold damage, and no bonus to initiative. Half HP takes a few seconds to come into effect due to BG3 engine timing. Max 2 skeletons per encounter on the Nautiloid.

Player-character level 4 or higher:

• Skeleton HP increases by 15 every 4 levels
• Cold damage starts at 1d4 and increases by 1d4 every 4 levels.
• +1 Initiative every 4 levels.
• +1 to-hit every 4 levels.
