Crafting and Automods

[mikeandroe]

I'm considering crafting a Safety Amazon Spear
I have a decent understanding of how the extra affixes are chosen, but I am curious about how the +1-3 Javelin & Spear Skills automod is handled.

If I understand correctly, the automod will be re-rolled when the crafting is done.

1) am I guarenteed at least a +1 or is it possible that the automod disappears entirely?

2) If the automod remains, but is re-rolled, does it use the same ALvls as the Harpoonists, Spearmaidens, and Lancers affixes? (i.e. will ILvl detirmine whether it's eligible for +3) or does it just pick randomly (33% chance of each) regardless of ILvl?

3) Am I correct in thinking that the automod does not prevent the selection of +1-2 Amazon Skills or +1-2 Javelin & Spear Skills from group 125 of the affixes?

Thanks
