is it possible to chance a two-handed weapon with a relayer deed to a one-handed weapon with the same special moves like before changing i.e. a yumi with doeble shot? So i can use a yumi but wearing a shield too?
And Next, a relayer can´t have weapon hits....if i change a yumi to one-handed and after that i add the levelable deed, can i add weapon hits then?
If you make a weapon one handed the only thing that changes is just that. You're not changing the type or anything so there is no reason to think that the weapon abilities would change.
When they say a relayer can't have weapon hits, they mean a weapon relayered to armor not a weapon relayered to one handed. It still hits so it can still have hits on it.
I have a few suggestions before you do this very expensive deed. Make sure you have an end game weapon, dont relayer some crafted yumi or some other nooby gear. For that matter, I don't think anyone really needs a 1 handed weapon. (I have several relayers and still havent bothered to 1 hand a weap.) IMO It is a very end game move so you are probably getting ahead of yourself. Relayer a shirt and skirt first with a bone crusher or SoT, get your stats up that way. (If youre not already) Get 220 dex done, costs about the same as a relayer for everything youll need.
