Valkyrie

The Valkyrie is a sword and one of the four refined options for Necron's Blade, that is geared towards the Berserker class. This sword specializes in and, giving one of the largest buffs of both at 170 maximum Strength and 60 Ferocity. In fact, this sword gives the largest Ferocity buff, overtaking the Shredder by 10.

Tips

 * This is the best melee weapon in the game due to its high Ferocity buff. While it is not the best weapon for single target damage, with swords like Giant's Sword overtaking it, it completely makes up for it from the Ferocity buff. This is also why it’s considered to be the best sword for Berserkers. Its +50% damage against withers is especially useful in Necron's boss fight.
 * In other aspects besides melee, its stats are severely lacking. In terms of using the Necron's Blade Scrolls, this is massively outclassed by the Hyperion and even the Scylla. Scylla would benefit the most from the Wither Shield Scroll, which scales off Crit Damage. The Hyperion gives 400-500 Intelligence, which is especially useful when using such a high mana ability.
 * If you are using this as a berserker, it is recommended to put the scrolls on the weapon, and wear a intelligence-giving armor set such as Storm's Armor to clear rooms. When in bossfight, it is recommended to switch to Necron's Armor to deal damage to Necron.
