For the tech tree in Total War: Warhammer, see Bretonnia tech tree (Total War: Warhammer).

The Bretonnia tech tree available to Couronne Bretonnia factions consists of technologies that unlock new advantages throughout the game. Research takes place constantly, but the rate at which discoveries occur can be increased by using heroes to spy or building additional research buildings at your settlements.

The Chevaliers de Lyonesse Chevaliers de Lyonesse has a slighty different version of the other Bretonnia factions, namely the part about Bretonnia heraldry.
