Do you people not know how to fucking use websites?

Jesus... I'll make it really easy for you to know what you can and cannot get on a rare ammy in 1.10:
http://www.battle.net/diablo2exp/items/magic/pre.shtml
http://www.battle.net/diablo2exp/items/magic/suf.shtml
You can get 3 yellow ones from each page or 1 blue(violet) one from each page.

Seriously... it's all there in black and white and blue(violet) and yellow.

Only actual skill points placed into a synergy count. No +skills are factored in.
