Greetings All,
First, I have not played or created a Warlock, yet. However, I've seen here on the forums and have been asked in-game on how to increase spell crits, etc. I will be IR'ing an Iconic into a Warlock soon. And it will be PDK/Warlock. I do my own thing and don't use a planner. Maybe I will share some more ideas after I run a Warlock to 28.
I listened to this episode of DDO Players News and I recomend it to you, because it's a good source of Warlock information. The info. starts at 21:32
BTW you can Cannith Craft both spell power and crits. You can make spell sticks and trinkets easily. I will probably craft a trinket for my Warlock, but here is an example of a spell stick:
Happy blasting,
Liv
