Every Wanderer has dealt with the disappointment of having poured so much
effort (and energy) into the creation of a vortex, only to have it fall apart
at the last moments. One particularly clever mage noted that a significant
amount of energy is released as a vortex unravels, and it seemed only right
that one should be able to harness some of that power. From this idea, 'Absorb
Magic' was born.
Whenever a vortex fails to stabilize, you are able to collect energy from the
fallout. The nicest thing is that you don't even have to have been connected
to the rift in order to get this boost!
