3rd Tier is a level that can be achieved in Fire Emblem Gaiden and Fire Emblem: Radiant Dawn. In Radiant Dawn, it is the final promotion for Beorc units. 3rd Tier units receive an Occult skill upon promotion, and can often have non-HP stats beyond the cap of 30, which is very rare for the Fire Emblem series.
In Radiant Dawn, 2nd Tier units can achieve 3rd Tier simply by reaching level 21, or by using a Master Crown when at level 10 or higher. However, in the Japanese version of Radiant Dawn, 3rd Tier could only be achieved via use of a Master Crown. 3rd Tier classes are incredibly powerful, but they typically have the same battle animations as their 2nd Tier counterparts. Some player units in Radiant Dawn start at 3rd Tier, and they include Bastian, Volke, Oliver, and Renning. Very few 3rd Tier enemies exist, such as Levail and Lekain. However, in Part 4 chapters, enemies have similar stat caps to the 3rd Tier units, although they are not actually classified as being 3rd Tier, instead being what are known as SP Classes.
