D&Dtools

You create an affinity feedback loop with all creatures within the area. While the duration lasts, affected creatures take all damage (including ability damage) as you do and heal all wounds as you do. For instance, if you take 10 points of damage from a sword wound, all creatures within the area also take 10 points of damage. On the other hand, if you are subject to healing psionics or magic, all creatures in the affinity field are also healed. Hit points gained or lost persist after this power ends.

Creatures in range are also subject to magical and psionic effects of 3rd level or lower (you therefore couldn't grant all nearby subjects the effects of greater metamorphosis when you manifest it on yourself, for instance). Creatures that have an affinity to you gain a saving throw against each new power transferred through the affinity field as if the power were manifested upon them normally. All magical and psionic effects transferred to subjects fade at the end of this power's duration, although instantaneous effects remain, such as the effects of curing power. If you suddenly become immune to a particular effect or power, such as might be the case if you manifested iron body on yourself, the effect or power to which you are immune cannot be transferred to creatures that have affinity to you.

For example, if you manifest animal affinity to gain an enhancement to your Strength score, so too do all creatures in range. However, even though animal affinity lasts much longer, when affinity field ends, all affected creatures lose the benefit of whatever power or powers still remain in effect on you. On the other hand, any hit point damage taken by subjects through the affinity field remains.
