skeletons should have different type of arrows depending on their biomes

In Minecraft, skeletons are one of the most common hostile mobs, appearing in many biomes with mostly identical behavior. This idea proposes a simple, logical change: skeletons keep the same AI and stats, but the type of arrow they shoot depends on the biome they spawn in. No new skeleton variants are required; only the arrows change. The goal is to make biomes feel more dangerous and meaningful without adding new mobs, complex mechanics, or fantasy-style systems. The design builds only on existing status effects, items, and counters already present in the game.
