Sara is a curious mixture - her offensive abilities are Strength-oriented while her miscellaneous/defensive abilities are Magic-oriented. She can either replace Clark as the healer character (who can also simultaneously deal damage), or both can be used in a dual-healer setup. Because of her ability pool, she can be specced as a fully offensive character, a fully defensive character, or somewhere in between.
Sara's heal differs from Clark's in that the initial base heal is less, but the Regeneration buff adds additional healing - meaning that she can potentially heal more than Clark, but the heal is given over time as opposed to one solid chunk. All her attacks notably inflict an effect on the enemy.
