If you're just getting into Hades after the full release of the game and are looking to upgrade your weaponry then you are going to need to collect Titan Blood. It is an important currency in the game if you want to continually boost the heat levels you are looking to complete after you finish up in story mode. We'll explore what you can do to get a whole bunch of this stuff so you can get stronger weaponry.
How to Farm Titan Blood
To get Titan Blood in Hades, you are going to need to apply a variety of methods to collect it. You will want to head to the Wretched Broker and hope to find a good deal, complete fated quests that reward it, switch on Golden Touch in the Mirror of Night and then buy blood at the Styx Shop, and finally you can also get two blood by completing a heat run. You get a blood for defeating the Furies, and another one for finishing off Hades.
The best way to farm Titan Blood is to go up in heat levels gradually. Try to complete each one with a different weapon so you earn one for beating the Furies and another for defeating Hades. You can also look to purchase one in the Styx Shop during the run, so you will sometimes be able to grab three in a heat. Switch out your weapon and for another run to earn more blood for that heat. Once you've finished a heat level with all of the weapons, you can then move onto the next one!
An alternative strategy is to just rush to the Furies with each weapon on each Heat level. This is far safer and easier than completing every run all the way to Hades. You don't have to risk getting killed nearly as much, and you can stack up all of the Titan Blood for each of the weapons!
Titan Blood Uses
Titan blood is used to unlock and upgrade the aspects of Infernal Arms. You will need a whole lot of it to fully upgrade each of the aspects. Each weapon requires 51 Titan Blood to fully max out the aspects. Each level you upgrade an aspect will change the look of the weapon and give you additional bonus to attack.
