I know that the generals are playable at opponents turn.
So the gems are not limited in quantity like special cards?
If i use gems from generals in my turn,can i additional attack with minions or heroes??(i think the use of gems is support action and i cannot do more in my turn)
Sorry for bad english.
Nothing like answering a year late...
When you play a general they get five gems. Expending gems does not count as an action.
