Okay, thanks. And I ment the one that increases the amount of summons.There are 2 Tier III Summoner classes. One of which actually reduces the ammount of Summons you can have active, but increases their affectiveness, and another that increases the ammount of Summons you can have, but makes them individually weaker.
The latter increases the ammount of Summons you can have as you level through it, although there is a cap.
