Quicken spell: While this metamagic feat is active, spells cast twice as fast and cannot be interrupted by enemy attacks, but they consume 10 additional spell points.
So you don’t even need a high concentration check to cast.
No, I wish they made they made the game harder, that would be awesome to see cleric be able to cast comet fall in a flash. I’d like to see enemy casters do what we do to them. Like cast a couple stone to flesh spells on our casters and clerics, chain cast damage spell on tanks. I really wish we could have enemy human controlled characters but then everyone would whine that they couldn’t beat quests lol
I’m hoping as the level cap goes up quests on elite will be more challenging, already with the new content I know several people who have beat all the new mod 5 quest including the raid on elite a couple of times.
