I'm revamping my mage for PvP and thinking about running a focused scribe mage with resist. With GM inscription I can run protection with +30 resist on jewels giving me 120. I'm wondering if anyone has experience or thoughts on this? Also I want to make sure I understand sdi caps correctly, as a focused mage the pvp sdi cap is 30, does the 10% sdi from inscription stack on top of this?
