Did I mess up? *Ranni's quest*

[Dirak2012]

I agreed to help her, and the selluvis guy told me to give some potion to someone (I don't really get the npcs on this game), and casually Gideon told me about that potion. Since I'm not the kind of person to poison innocent people, I went on with his alternative... Now selluvis is dead (I did got some cool clothing) and I don't know if I ruined ranni's quest.

Nah he just dies if you give ranni the thing she asks for.

[Willcutus]

No, you are fine.

You can mess it up if you progress Seluvis' quest enough to give Ranni the Amber Draught, but even then you can just atone at the Church of Vows and then continue on like it never happened.

NAh you did exactly whats right

[Bonkers]

While you did miss out on getting either Nepheli or the Dung Eater as a puppet (spirit summon), which would also ruin their questlines in the process, you didn't do anything wrong or miss out on anything important.

Personally, I like to use the potion on the Dung Eater, wait until his animation finishes and then kill him to get both his armor as a drop from him and the Dung Eater summon from Seluvius.

Seriously, who makes this "quests"?

You have to rest in a certain spot, look for random line of text that pops up, and repeat the same meaningless dialogue several times before the quest can continue...
There is something to be said about excessive handholding, but this is absurd.

at the Mistwood Crater, Blaidd left a message that said he won't come to Nokron with you as there's a traitor he need to deal with (refer to Seluvis).
if you talk to Iji, he also will said the same thing.
