Brio: Grants Mov+1.
Guide rating 5 out of 5 stars◇ our recommendation: this guide's own judgement, not a sourced fact Permanent Mov+1 with no condition attached is one of the strongest personal effects in the game: more tiles every turn, on a mandatory Lord. Rate it yourself

Exploration talent
Create a Field on a Tile to Farm Crops: During exploration, Cai can plant crops on empty land. You must wait a couple turns before the crops are available for harvest, and you can see when they're available by checking the progress bar in that area. You can also fertilize your crops using Manure or replace them with a different crop. These crops can then be used for different purposes, such as trading or feeding the Pale Raven.

Story and profile
Who they are
Cai is a lord from the Ribeira Winds, a village boy whose father Castor taught him to fight, and he entered the Heroic Games to save his father's life. He likes physical training and catching animals. Tialla is a childhood friend from the same village.
Cai starts as a Commoner with 45% growths in HP, Strength, Dexterity and Speed, and 35% in Defence and Resistance. Brio gives Mov+1, which is why the guide points him at mounted classes: Ornius Rider, then Light Cavalry, Bardinger and Orichaldia. The guide author finds Bardinger weak, so keep him in Light Cavalry where you can. Diadem of Duality adds Atk+3 on a 25% trigger, and as a main character he can use Blaze Arts. Sword, Spear, Rider and White Magic are his preferred skills; Bow and Flier are bane skills. His exploration talent lets you plant crops on empty land and harvest them after a couple of turns. He is ranked S.
