The Kronen resurrects a lethal fighting style once thought lost to the ages.
The Kronen are a pair of bladed Tonfas that were added into the game in Update 14.5, and second of the fan-made weapon designs from DE's Community Melee Weapon Contest to be implemented, the first being the Silva & Aegis.
As with all Dual melee weapons, the Kronen consumes Stamina per individual swing of their left and right weapons. Since dual weapons can swing twice in rapid succession, one can drain stamina at an alarming rate faster than even stamina-heavy weapons like the Fragor. Consider using the Quick Rest mod when wielding this weapon to quickly recover Stamina, or alternatively use the Second Wind mod to instantly regain Stamina on channeling kills. Using Melee Combos that hit multiple times per attack like Gemini Cross' Vagrant Blight can also offset the heavy stamina cost.
With melee auto-aim on, you will be reduced to a very slow pace when your character chases down running enemies. Often, in the case of targeting a fleeing Grineer Lancer for example, the speed at which you move forward to attack is nearly equal to his run speed, meaning you will continue to swipe at him without hitting him until he stops moving.
