Crimson Bullet
This is a pretty nice skill in Aika that most PvE builds like to max this, and. Max this if you have the points, it's very decent in PvE. Also, the 50% heal penalty is almost needed if you want to fight Archmage Sedin in Lost Mines Elite, since his heal usually out heals all your DPS. Good on those pesky clerics too. Also, keep in mind that this will never kill anything, bringing them down to 1 HP (aika gold) at most, which make it a great bot-killer if you don't want the infamy or honor loss. Go ahead, molest those pesky bots with this skill!
Eagle Eye
Some people like this skill for honor hunting. 60 second buff with 120 second cooldown means you can only have this on half the time, and your main skills have natural crit bonus anyway.

Concentration
A decent passive that give you less chance to be interrupted and hit rate. You might want to put more skills points into this if you like PvP and solo questing. 1 skill points is good enough for general dungeoning.
Sharpshooter
Very nice passive that increase your Hollow Point crit even more. Max this, this let your crit deal more damage than a double.
