I dont understand how the blood works

[POLINCHI]

I mean, i get tha it gets worse as time passes by, BUT, the game told me that you cure it, i should give my infected hero some blood, and i did, but it didnt cure it :c and the character had only lvl blood.

Did i miss something? do i have to give the guy more blood? and how do i get it?

When a hero gets the Crimson Curse, CC, they will be in on of the following states; Bloodlust, Normal, Craving, Wasting or Dead. Over time, either weeks passing, tiles moved in a dungeon or turns in combat, the status of the character will decline through that list. The Blood is used to treat the CC, but will NOT cure it, there are ways to cure the CC but I'll avoid mentioning them as not to spoil anything. The Blood should be given when heroes are in the Craving state, shown by their character bleeding, or the Wasting state, shown by the character being followed by flies. Giving a character in Bloodlust the blood is bad, giving a character in Normal the blood is pointless and giving a character the blood while dead is impossible. A character who is Wasting that is giving blood will turn their state to Normal, while a character in Craving who is giving the blood will turn their state to Bloodlust, which acts as a temporary affliction if anything, but does give combat bonuses. Blood can be gained through a number of different methods, such as a district known as the Sanguine Vitners, which is what I use since I am lazy, but can also be gained by interacting with curios on dungeons, fighting CC enemies or going on "Collect the Blood" missions in the CC.

When you first get the Curse, you start out in Passive mode, which has some minor debuffs: -5% Stun/Blight/Bleed resist and -10% max HP. It also has a minor speed buff, +1 SPD.

This state is otherwise harmless.

This lasts 31-75 rounds, the exact length being random.

(Staying in the Hamlet a week counts as 30 rounds.)

Then you pass into the Craving state, which is dangerous.

The debuffs are -10% Stun/Blight/Bleed, same -10% HP, -10% Virtue, but the speed buff doubles to +2 SPD.

However, you take random actions like an Afflicted hero, stress other heroes out, attack other heroes, refuse to eat in camp with massive stress/damage, and act on curios.

This lasts 31-46 rounds and moves to the next state, Wasting.

Wasting is right before you die, and you will die on the next check.

Same -10% Stun/Blight/Bleed resist, -20% max HP, now a huge -4 SPD debuff, and -10% deathblow resist.

The involuntary actions are even worse and often include passing.

This lasts 61 rounds and then you die. (And if you have a hero in the Hamlet in Wasting state, they will die while you are gone unless you have Blood when you get back. When you're provisioning for a mission, there's a thing on the left with blood dripping and if you mouse over it, it will pop up a tip telling you how many Wasting heroes you have.)

You want to administer Blood in the Craving state. In the Wasting state, you have to administer Blood or die.

In the Wasting state, administering Blood does nothing but take you back to Passive and start the cycle again.

But in the Craving state, Blood puts you in the Bloodlust state which has huge buffs.

+25% DMG/+4 SPD/+25% Stun resist/+15% Blight resist/-10% Bleed resist.

You also take random actions, but often they're actually good, like randomly healing your own stress. You still stress out/attack other characters/move around involuntarily/use random skills. But when they're attacks on enemies they're often seriously damaging.

This state lasts 22-30 rounds.

You can also administer Blood when in the Bloodlust state, but it's extremely dangerous.

You immediately take 35-40 Stress but get +50% DMG and +4 SPD on top of other buffs. You usually shouldn't do this but sometimes in an emergency it gives you what you need to finish a fight like a boss fight.

I've only done this two or three times but it worked, so you should know it's something you can do. You just usually shouldn't.

All of this is in the Wiki article and may change.

Also you can mouse over the passive/craving/bloodlust mini-icon over your character's HP bar to see exactly what buffs/debuffs are in effect from the Curse.

Another nice thing is getting the Curse immediately cures all other diseases you have and you can't get other diseases while you have it.

You get Blood from drops from monsters sometimes, and also you can go on a short length quest in the Courtyard specifically to get it.

No, the blood just helps with the negative states of the curse. If the hero is craving and drinks blood he becomes bloodthirsty and if he is wasting and drinks it he will become neutral. Only way to Cure cure it is to either beat a boss in the courtyard or get a cure potion from the heretic when you beat him.

[madzero]

or when you beat the countess:you'll be able to cure it like anything else after that
