All Drukhari units have a Pain ability, tagged with the word 'Pain'. Pain abilities only apply to a unit while it is Empowered. If your Army Faction is Drukhari, you can Empower units from your army with Pain abilities by spending Pain tokens (see below).
GAINING PAIN TOKENS
If your Army Faction is Drukhari, you gain Pain tokens as follows: ■ 1 Pain token at the start of your Command phase. ■ 1 Pain token each time an enemy unit is destroyed. ■ 1 Pain token each time an enemy unit fails a Battle-shock test.
Each time you gain a Pain token, keep it to one side – this is your Pain token pool. Each time you spend a Pain token, reduce your Pain token pool by the same amount.
EMPOWERED THROUGH PAIN
Each Pain ability will state when you can spend Pain tokens to Empower that unit. When you do, until the end of the phase, that unit is Empowered and all Pain abilities it has take effect. While an Attached unit is Empowered, the Pain abilities of all Leader and Bodyguard units in that unit take effect - you do not need to spend additional Pain tokens to activate each of those Pain abilities.
