Forged in Hellfire |
Forged in Hellfire is the ultimate Light Cone of the Mortenax Blade. Honkai: Star Rail. His signature Light Cone gives him a huge amount of base HP along with additional HP% due to his passive effect. That alone significantly increases Blade's maximum HP and DPS. Reforged in Hellfire also regenerates Blade's energy, which is essential to his kit. Blade and his team must be within the Ultimate zone. It's important to keep your ultimate active and available at all times.. Additionally, when Blade uses Reforged on the Hellfire Light Cone, he will apply a debuff to enemies, allowing him and his allies to deal 30% more critical damage. Blade himself deals an additional 30%, making him one of the best DPS supports. high speed rail. I recommend purchasing the Light Cone for your Mortenax Blade. Because Mortenax Blade will be run by multiple teams and he's not going anywhere anytime soon. This Light Cone allows Blade to deal maximum damage while providing excellent support to his team. It's a whole new level Honkai: Star Rail. |

lies dance in the wind |
Lies Dance on the Breeze is a good Light Cone for the support aspect of Mortenax Blade. Blades can further reduce enemy DEF. Ideally, Blades should use this 5-star light cone to reach 170 SPD when competing against the S5 4-star alternative, which also reduces enemy armor. However, you should not sacrifice your blade's stats to increase SPD. He should reach SPD 170 through Light Cone's passive effect, sub-stats, and buffs gained during combat. That makes Lies Dance on the Breeze one of the best light cons for Mortenax Blade. high speed rail. |
|
Holiday Therme Escapade |
The Holiday Thermae Escapade is a great light cone choice for the Mortenax Blade. Honkai: Star Rail. At S5, the DMG of all attacks increases by 32% and the DMG received by enemies increases by 16%. What makes it a good choice is that it allows you to increase your DPS without compromising your role as a support player. |
|
Determination shines like pearls of sweat |
Resolution Shines As Pearls of Sweat is more of a toned-down version of Lies Dance on the Breeze Light Cone. At S5, reduces enemy defense by 16%. This is the standard version of the 5-star Lightcon's passive effect. |
|
infinite choreography |
Blade can reduce enemy DEF in Ultimate Zone. This means that the S5 in particular will be able to make good use of the Boundless Choreo Light Cone. The idea is that the blade can deal a lot of extra critical damage to enemies affected by the DEF reduction debuff. Additionally, Light Cone provides a large amount of crit, so it's safe to build Blade with Crit DMG as the body's main stat, opening the door to massive DPS increases. Boundless Choreo is amazing for Blade's DPS, but it doesn't rank as high as the other Light Cones on this list because it doesn't offer anything to his team, which is Mortenax Blade's core strength. |
