How often do sigil of power drop?!

[Noxina]

Nah, can't remove them. You just buy extra ones after completing the quest, for 10,000 gold each I believe.

What I don't get though is why bother allowing us to stack extra sigils if they aren't going to be used? I've got 18 sigils of power in my bags, and I figured that you could use extra sigils to get more gems (maybe not another 10 of each, but like 3 of each per extra gem or something). But no, apparently not. 10,000 gold please.

Ah well. I definitely won't bother gemming an LFR weapon if I happen to get it: my guild has killed both Tsulong and Shek'zeer on normal mode, so it's only a matter of time until I get one or the other (Gao'rei/Claws of Shek'zeer).

10,000g seems to overpriced :O But looks like Blizzard are realy going in for those gold sinks this expansions :P Good things I guess, but I dont got the gold for all this..

MSV = Power, HoF/ToES = Wisdom. Might actually get gem before the Terrace 2h axe drops.

Actually TES dropped Power as well, for some retarded reason. Have 20 power, 6 wisdom :|

Often enough, done 2-3 clears of mogu'shan vaults. And got 10 sigil of power.
