So in light of my testing and confirming Dethek Runestone is only providing +1W on Lammania, I thought about ways to possibly give the shield a bit of a facelift in the light of Ravenloft and other endgame gear the past couple of updates.
I've really only got a couple suggestions at the moment, but I'm sure other people have some as well, that's the point of this thread.
1. Drop the minimal level to 24. Halve the current level as it's not really worthy of the 28 requirement due to my next suggestion.
2. Bump the 15/adamantine to 30/adamantine in parity with both stage one Shadowdragon Plate and Bloodrage Chrism.
3. Remove the DR all together and instead slap on Profane/Primal bonused PRR/MRR. Say 10-20, not a massive amount.
4. Add Healer's Bounty, perhaps in place of the current Runic Revitalization.
5. Add a 10% SP reduction.
6. Add more of the on-hit buff/temp abilities such as: Demonic Shield, Concordant Opposition, etc.
7. Add an epic Earthgrab proc or a no-save Earthgrab proc, after all the effect is called Stone Paws.
Edit: I probably didn't make it clear. Any of these, not a combination of them would help. Although I'm certain more than one might help revitalize Fire on Thunder Peak.
