Creatures damaged by your powers with the cold descriptor become entangled.
Benefit: To use this feat, you must expend your psionic focus. The frost of your cold power clings to the target, impeding it for a short time. A rime power causes creatures that take cold damage from the power to become entangled for a number of rounds equal to the original level of the power.
This feat can only be used with powers that have the cold descriptor and deal damage. Using this feat does not increase the power point cost of the power.
