Been running FR realms content on my Bard 20/Fatesinger. A few things I need to work on...
Get a perform +15 item. Stormsinger cloak won't cut it anymore.
Upgrade my silver flame pendant to a silver flame talisman. Protection from evil items are bugged though so that makes me sad. Greater command is not my friend.
Get more spell pen in my enhancements, and also look at shifting away from melee focus to cc focus and get spell pen feats too. Crafted an epic scimitar of cursespewing/improved shattermantle to help with OID at least, along with a spell pen buckler.
