Clears any negative status effects (i.e. poison) immediately, and performs a large DELAYED heal. When capped, it will usually completely restore your health bar from almost zero. Be advised, the battle cry doesn't linger. Once you "cry" it works and disappears, meaning if it heals your poison and then you catch fire, you will burn. But don't worry, within seconds of the effect clearing naturally, you will have all your health back from Idunn's Touch. Both my Human and Cyber Bio Engineers max this skill and cap off their healing effectiveness. The result is that I can continue to fight while poisoned or on fire and my healing won't let my heath drop below 90%.
