The Spirit Realm

Topic pretty much says it all, if i plan to tank as a paladin where should my first 100 AA's go?

Well I went the route of the AA horse (no unicorn),some Combat Ability and Stability, and then would get some Slay Undead.

If you solo most of time, slay undead all the way, follow by basic level of CA, CS, ND, Speed of knight, Knight's advantage etc. If mostly tank in group, do mostly tank stuff. Horse and run AAs are the only utility ones worth the mention in first 100.

Metabolism isn't bad either especially if you plan on getting the horse.

First 3: Run 3
2nd 3: Innate Metab 3
After that, Natural Durability i think its called...its a small boost into like 3 different things.
Holy Steed
Slay Undead after that.

Physical Enhancement, Knytul? That AA is only functional if you have AA already in Combat Agility, Stability, and Durability. The first three ranks of each of those AA are good candidates for "first hundred", though, too.

There is no longer the requirement to spend 6 in general, 12 in arch before doing the class stuff. You can just skip directly to whichever AA you want provide you satisified the level and pre-requisit. If you gunning for slay, just run-3, combat fury, then slay undead. The increase in speed of killing easily compensate you for doing it first if you solo much.

Yeah I recommended Metab 3 more for a convenience factor I hate having to make or buy more food. It didn't seem that important til I got it now I can't live without it.

It is also hard to argue with more spell slots and/or buff slots, depending on your play style. Not the sort of thing you can quantify like CA or ND, but you may find that it saves you tons of headache to invest some AA in those. If you don't raid, the buff slots may not matter at all. If you do, they can be a godsend. In any case I doubt I'd max out those two in my first 100 AA's heh... just good to keep them in mind along the way to figure out when the pain point becomes great enough to justify spending some AA's on them.
