This build is absolutely impossible to kill. Not only do you have immense amounts of health, but you have a ton of armor, which is buffed with your 4th ability, a complete immunity to status effects, and a 12% chance to heal 24% of your health every time you take damage (a 6% chance to heal 48% of your health) due to your arcanes. Even if you somehow manage to die, your bleedout ability lets you revive yourself in almost every case, so it actually takes a conscious effort to die with this build. You don't really have much in regard to damaging abilities, so you need to rely on high-damage weapons like [Tigris Prime] and [Rubico Prime]. The buffed melee damage is specifically because you want to equip a [Hirudo] to further buff your healing or a [Redeemer Prime] with a full condition build for an absolutely ungodly amount of damage (with [Bullet Dance] stance).
The only downside to this build is that it is extremely selfish and lacks any real form of utility or buffs that benefit your party. You just do your own thing, faceroll any enemy, and leave the buffing and healing to everybody else.
