Preservation or SLW?

Hi, I was wondering which is more useful. And also should I use my tome to get SLW or Ritual Lord? I already have Preservation. Thanks!

Sell the tome for cold, hard cash.
If you've capped Preservation, then you're in the right area to cap SLW and Rit Lord.

Personally, I wouldn't use either SLW nor Preservation - Preservation sucks, period, and SLW is essentially an elite Healing Breeze. Heal-over-times are bad in GW, as a rule of thumb. And SLW stops you from having a more useful Weapon spell on - Splinter Weapon (... which you're using, right?) which kills shizzle; or Weapon of Shadow/Warding which stops stuff dying.

Better yet - assuming Factions only - would be Attuned Was Songkai or Signet of Spirits if you really must take a Rit elite; or Expel Hexes or Empathic Removal if you really don't care.

Hard truth about Rits - most of their elites suck.

Well I have all the games but I capped Preservation in GWEN. So which skill out of the 4 you suggested would work best for RA? My other skills are: Mend Body and Soul, Spirit Light, Mighty was Vorizun, Soothing Memories, Recovery, Remove Hex, Weapon of Warding. Thanks again!

Drop Remove Hex for Empathic Removal, add in a Res Signet.
