When do you know something is really good? How about when its good enough to put it on one of the few legendary weapons WoW has? As many of you know with the introduction of Ulduar blizzard implemented on the game the first level 80 legendary they made it a one handed mace for healers as shown here: Val'anyr, Hammer of Ancient Kings as more raid came out and the gear started to get higher and higher this mace became less and less good stat wise, but what makes it legendary you ask? well simply Blessing of Ancient Kings will always make it legendary even at level 85 who knows. The reson is the better the gear the bigger the heals, the bigger the heals the bigger the shields.
Now you might think that blizzard came out with this idea after patch 3.0, well think again because it was just a copy of a trinket dropped by Viscidus an optional boss in the Temple of Ahn'Qiraj ( 40 ), a giant slime with quite interesting mechanics that I hope to see more often in Cataclysm. and here is the trinket Scarab Brooch tada!
This trinket is a use trinket and when you click it you have a 100% chance to shield any friendly allies that are hit with ANY of your healing spells. The good thing about it is that you can basically chose when you want to be able to shield people rather than the 10% proc chance on the weapon. This does not make this trinket better than a weapon of course because the weapon might not have the best stats but it has something and the trinket just has nothing, but if you can get your hands in a 284 item level LK H weapon like Royal Scepter of Terenas II I personally think you you change it with the legendary for some fight where its shields turn out to be at the bottom of your healing done, and the best you can do is use the legendary weapon and the trinket at the same time for damage heavy fights and time you weapon proc and once its up use your trinket and boom it became 30% shields and with the current 25% ICC raid buff its just stupidly crazy we finally can beat priest! ( not really that will never happen)
