Solo Paladin build?

[pasi]

Stack things that increase your killing efficiency - AC/STR work well. Wisdom is weak in comparison as Godbox covered.

The biggest things I can recommend aside from gear suggestions are

1) The spell Courage. Use this as your main downtime heal until 30. Time it with your sit regen ticks to minimize downtime. The HP per mana on it is much better than minor healing and light healing. Light healing isn't terrible to use between melee swings (another reason 2handers rule). After a melee round, hit F1 and alt+# then F8 really quickly.

2) You have a huge exp penalty. Avoid low ZEM zones if possible. From 15 or so until 41, you should probably stay to Unrest. There's groups, high levels for buffs frequently, a nearby city with a paladin's guild, a huge ZEM, decent loot (small bronze), an easy escape route, undead galore, etc.

If you absolutely must solo in an outdoor zone - try to find room (i.e. no adds) to joust a mob with a 2hander (Baton of Faith). It's a lot more efficient than straight up tanking.
