Overall
Sierra has sub-par growths and will result in her having lower stats than the rest of your attack Mages. Her Luck, Defense, Agility, and Skill are where she suffers most in comparison to her peers. Despite her statistics, Sierra sells herself as a useful ally with some unique abilities. She is effectively the only ally at your disposal with the Warp skill. This allows her to teleport to any maneuverable place on the map, allowing her to provide special support such as: protecting treasure chests, killing off thieves, healers, ballistae, opening doors earl, supporting recruitable allies, and providing the killing blow to an enemy which no-one else can reach. She is your only ally who can use Dark tomes, some of which are very useful and work well with Warp: Janura drains HP, Evil Worm and Tomaharn can attack from 3 spaces away, and Earthquake can attack all enemies on the map. She is a very useful character, but may need some stat-boosters to augment her stat growths or she may get herself into a dangerous situation pretty fast.
