I like Ninjase's [Mag] build but it is Very Fragile with nothing but [Rolling Guard] for survivability in hard content. This build will kill everything in Steel Path, and you wont die, and you wont have to roll with precise annoying timing for invulnerability.

1. for full armor strip, use one archon shard for strength (essential to build)
2. for survivability use 3 armor shards for increased damage reduction.
3. The 2 arcanes are completely 100% flex.
4. [Adaptation] for survivability
5. [Magnetized Discharge] is very useful for crowd control, but not essential either. Add range for a variation.
6. Pull is excellent crowd control and you dont need Magnetized Discharge because Pull ragdolls almost everything and enemies cannot shoot at you -- so why bother with a disarm augment?

The key to any [Mag] build is refreshing shields regualarly, and she has 2 different abilities that do that.
