[Taboo Halo: Within the halo's range, the attack and defense attributes of the summoned spirits will be increased by 3 points. Stackable with other halos.]
The attack and defense attributes of spirits could be increased by a maximum of 3 points at once. The attack and defense attribute that these spirits possessed represented their strength and the higher their attack and defense values were, the higher their levels were. If Rhode unlocked Gillian's seal, she would be one of the spirits with the strongest levels at 20 points of attack and defense.
There were no preconditions in using this Taboo Halo to 'temporarily' increase the attribute points by three for all the spirit cards. In other words, every spirit that he summoned within the halo's range would have a +3 buff to their attack and defense attributes.
