Dragan Weapon Augment Crafting (bow)

I am new to crafting but since I have recently reached level 55 this is probably something I should invest in.

Currently I'm equipped with T0 Dragan's Incensed Bow. Went over to the crafting dock where it tells me I need 100 Draken cores and 100 Augment cores - the amount not being of consequence - but it also says to increase the tier of the item I require a T1 leg bow with the same number of slots. Have collected a few T1 leg bows with 4 slots (same as the unique) and have tried to insert them but it tells me it's the wrong type of leg item? Unsure if there's a specific bow I'm meant to farm for or if I'm doing something wrong in general, so just a few questions:

1. Anyone know the type of leg bow or have an image of it that I should be using?
2. Anyone have any useful links for crafting?
3. Is the only way to obtain a T1+ leg item via farming?
4. Also if I use pristine core crafting and transfer the enchantments, would I lose the enchantments I currently have on the unique or would they just be added to the 2 present enchantments already..?

Thank you.

 

Basic answer - don't do any type of crafting with your t0 bow..

More complicated answer - there's a crafting primer on the wiki and here. Google "drakensang online wiki" or search for "crafting" on the forum.

If you want to stick with 2H bows at the moment, what you should try to do is obtain higher tiered pw bows (especially heralds) or the blood rune bow.
