I am hoping someone can enlighten me on a few topics. This game confuses me beyond belief and is nothing like any other mmo i've played.

1.) I'm level 28 and stacked all magicka. Would it be 100% pointless for me to use DW? I want to use daggers. I'm a nightblade. Wouldn't not having points in stamina make having DW be comepletly worthless?

2.) My friends and I duel alot and no one ever dies. It takes over 200-300 hits to kill each other. Is this intended?

3.) As a mage night blade, should I only use staves?

4.) How do I get more than 5 abilities on a bar? Or am I supposed to just play through the game with 5 skills?

Check alcast guides and/or just try some specs. You can "reroll" all points set for gold

Not sure on the first two, havent played nightblade much.
But yeah as mentioned above check alcasthq, he has the best guides, or deltias gaming.

As for #3 the skill bar is 5 skills and an ultimate. But you get two bars, one on main hand, and one for back-up. So you can have a total of 10 skills, amd two ultimates split across two bars. If you want to switch between the two, you could get the exact same weapon for both bars, and then use it that way if you wanted to.
