I looked at rogue, and the powers seem to all require light blades. I only the initial books. What book is the monk in?
Monk will be in PHB3 next March, but it can be playtested if you have a Dragon subscription.
Short answer: the only way to
effectively fight with a spear using Dex is to be a member of a class that a) uses Dexterity for attack and damage with its powers and b) is capable of using spears with its powers. Right now, only a few classes use Dex for their primary attack stat:
- Rogues can't use spears with their powers.
- Rangers use Dex and can use spears, but only when making ranged attacks. You could be an eladrin javelineer as a ranger.
- Monks can use spears with all their powers and attack with Dexterity.
Right now, monk is your best choice. You could also take the Melee Training feat from PHB2 that lets you make basic attacks using Dex, but that won't help you with attack powers.
Finally, if your DM is willing to house rule, Martial Power has the Tunnel Stalker feat, which allows dwarf rogues with Str 13 and Con 13 to treat one-handed axes, hammers, and picks as light blades, at the cost of one die of sneak attack. Ask your DM if he's willing to change the feat to n eladrin racial feat called Woodland Skirmisher, which requires a 13 Str and 13 Wis, and allows you to treat longswords and one-handed spears as light blades at the cost of sneak attack.
