Tama's Autoskill Samurai Guide

As what Mahou said earlier, it's personal preference really. 

Hmm, you can easily compare your question as to why the need for more agi by comparing a 1agi class to one with 400agi with the bosses that are around right now.

Nope as far as I know but agi gives you the same attack dex gives. 

although this might be inevitable during boss fights, i suggest to rebuff shippu every time you're done with killing the mob instead of buffing in the middle of killing as mental clarity might get cancelled when you get hit by mobs' magic attack. personally i have never had a problem regarding skill delay when rebuffing shippu and i have a lot less dex compared to agi. hmm..

You do not have to worry about missing cause of absolute clarity. This assuming you do not have -crit rate % gears. 

How about veleno rosa xtal?it is good for autoskill samurai?

Argent ring for mp set,another option beside orichal ring.

Orical would be better since it adds 1k more mp, argent might be good if you have low dex and need to buff shippu quickly-er tho

Righto o.o/ also 220 is a good time to switch, i pretty much lvled from 220 to 240 in a couple of weeks just doing hardcore mega, no books just grab a mp healer and go to town

Also for lvling spots theres a really good one before nuitraim, any sword, any armour,a hcb and any spec, gives 20k exp,trash hit rate and low hp o.o but best of all it auto atks you so u can do it without paying much attention

And mobs on floor 44 of eternity maze, you rarely get hit with 300 ish eva+ it gives more exp then ents and auto attacks you so u can afk lvl(also drops rev l o.o )
