Each overworld terrain tile has a specific [[Tier]] associated with it, as shown in the numeric map overlay below. In general, a tier represents the minimum level in that terrain. The surface zone tiers range from 0 to 5. For a Tier 0 terrain, it is expected for level 1-5 creatures to roam around freely. For Tier 1, 5-10, etc. This is not a hard limit, so creatures outside of these tier values are able to appear, though will generally appear at a much lower frequency.

Apart from Tier being a difficulty indicator, it also is used to generate the location of {{favilink|Kindrish}}, which is always in a terrain with tier 4-5.

As you descend downward into into the strata beneath the surface, zone tier increases by 1 per five levels downward, to a maximum of 8. So, for example, if you enter a {{favilink|Ruins}} biome (Tier 3) and descend to level 13, the area you are in will be a Tier 5 area.{{Code Reference|namespace=XRL.World|class=ZoneManager|method=GetZoneTier}}

{{Main|Underground}}
Underground, tiers also change depending on how deep the strata is. For the first 5 floors, the tier will be the same as the overworld terrain. However, past that, the tier is the absolute value of <math alt="Z level - 6 both divided by 5 plus 2">\frac{Z-6}{5} + 2</math>. This means that the difficulty and rarity of items increase the deeper the player character goes.
