[Spoilers] Find the next remnant, bring me stuff to bless?

[Kamamura]

Well, I am at the end of the game, collected all cherubs, found every room, but these two still want something - Cleofas and his order (via that church window) want me to "find the next remnant", and the feet washing deity in the saltpeter dream wants to "bring me stuff to bless".

Is there any, or were the devs too lazy to conclude the quests?

Check if you have Debla of the Lights prayer. If not, you are missing something from the remnants of Tentudia. There is one remain near the entrance to Mercy Dreams (need blood platform relic to get), one in Where Olive Threes Wither in a passage below the entrance to Graveyard of the Peaks, and in the peaks themselves (I think you need both blood platforms and the vine relics to get this one). Once you give them everything and also finish Cleofas' quest, they won't speak anymore.

Check to see if you have these relics: Shroud of Dreamt Sins, Incorrupt Hand of the Fraternal Master, and Three Gnarled Tongues. If you are missing one, you need to bring it to the deity to finish its quest.

The shroud you get for bringing one healing item for Tirso (Linen Cloth), the hand is in Desecrated Cistern in a horizontal room with a body, near the entrance to a blood fountain (it's a hidden path you need to slide under - you also need the relic that allows you to walk through swamp to get it), and the tongues is the reward for doing the whole Altasgracias quest (it's the vine summoning relic). Once the deity purifies these 3 items, it won't speak anymore.

Fantastic advice, thank you! Turned out I really missed one of Tentudia remains (from below the bridge), and I forgot to return for the severed hand after I learnt to jump in mud. Both questlines are now finish, thanks again!
