你可以去ufopaedia查, 裡面有很多XCOM的資料
成為靈能兵的機會
The Psionic Lab will allow you to test your soldiers for psionic powers. You may test up to 3 soldiers at a time, upon which they will be unable to join a mission during the 10 days testing time.
The chances of a soldier becoming Psionic depend on several factors:成為靈能兵的機會取決於
The soldier's Will stat. 士兵的意志
Its rank 士兵的軍階
The number of already existing Psionic soldiers 已擁有的靈能兵數量
Whether Second Wave's More Than Human option is activated or not. 第二波選項是否有開More Than Human
If activated then the number of tested soldiers will count until you received your first Psionic.
對於少校或上校軍階的士兵
Psi Chance = Soldier Will / 4
也就是意志力80的少校或上校 成為靈能兵的機率是20%


士兵意志成長(初始40, 每次固定成長2, 隨機成長0~4, 若軍官訓練學校有買Iron Will, 可以再加


其他可以自己查查ufopaedia~
