I really don't know if someone has posted this ( if made some search first and nothing about this kind of farming). To farm Superb Charr carvings you must enter into mission Nm ( mission is " Warband of Brothers" from Gron Fierceclaw in Doomlore Shrine) . Enter Mission ( title up Rebel Yell ) and kill all those charr. Best way to kill them is again with SoS Rt, but only lvl 1 Solo ( posible lvl 2 and 3 but takes to much time). For better and faster farm you can take a friend with Rt or Any/rt with SOGM ( Signet of Ghostly Might) , and clear all 3 lvl .Here is the build for Lvl 1 solo( not to many modification).If you die don't worry you will be resurected at the shrine.

If this doesnt work:
Elite: Signet of Spirits
Vampirism
Bloodsong
Pain
Anguish
Armor of Unfeeling
Ebon Vanguard Sniper Support
Painful Bond
Communing +12 , Channeling 15 ,Spawning 9
If someone else come with better ideas pls posted here. the build works good for me ,but you can change however you like it.

This is what i solo war band with well the 2 lvls tried to do lvl 3 but need a bit more practise into where putting the spirits 
this is the build I use http://pvx.wikia.com/wiki/Special:PvXDecode?title=Special%3APvXDecode&wpBuil d=OACkAmhjITi01kPY503UnI00mY1E&wpName=The+keepers+ code&Go=Submit+Query
with a superior spawning on the helm so that's 3+1=4
and major channeling +2 -35hp
and a minor communing
the rest is pretty much health and energy with ritualistic shadow staff a green

Ok, I did a solo test run for this and used loopysnoopy's build (replaced spiritleech aura with summon spirits, I like to carry the spirits along also better healing).
Cleared level 1 with no problem got 4 carvings.
Cleared level 2. In level 2 had some difficulty with crowded char groups and ally chars as they messed my luring, got 7 carvings.
Cleared level 3. Got 10 carvings. Died twice with Effigies.
In total: Took more than 1 and half an hour. Got 21 carvings, 2 gold xp scrolls, 1 white dye, about 1k gold, 1 gold item, and lots of materials from salvage items.
Result:
Was it fun?
Yes.
Is it worth to do?
Not the drops but I like solo play..
Will I do it again?
Don't think so.
A faster way for getting SCC, farm ectos, shards or gems, sell them, buy carvings
