Shera has a 25% spark reduction buff for 1 turn for 40sp, that alone makes her a pretty viable mitigator to bring for survivabilty content in my opinion. Endless corridor is a good example of where she can be really useful, waves of multiple units that can and will spark. Even more useful if there is a spark buffer unit on the enemy team.
