Reinforcements are units that appear on the map after a chapter or battle has begun. Reinforcements are typically enemy units, though they may be allied or even playable units instead.

Reinforcements can have a variety of triggers, though the most common one is at a certain turn. They can also be triggered by reaching certain areas of the map, defeating a certain number of initial enemies, and various other means. In many cases, reinforcements will spawn from forts or stairs, and can be avoided if the player places a unit on the same spot that a reinforcement comes from. Sometimes, an enemy unit may block further enemy reinforcements, though these cases are rather rare. This tactic is not always possible, however; in Path of Radiance, Radiant Dawn, Fates, and Heroes, they can simply appear spawn from a space adjacent to their normal spawn point if it is blocked.

In most games, reinforcements will not act on the turn they appear, though there are some where this is not the case. These are often called "same-turn reinforcements" or occasionally "ambush reinforcements" or "ambush spawns" by fans, and can be some of the most dangerous kinds of reinforcements, and can be much tougher to plan on without knowing when they appear ahead of time. Regardless of this, reinforcements will typically act as soon as they are able, even without being provoked by another unit.


Depending on the game, reinforcements will appear at different points during a turn. These timings may also change with difficulty. Certain reinforcements with non-turn-based triggers may appear at different points in a turn from what is shown below; these are noted on each chapter's reinforcement section.
