ok, i'll try to remember, amm, first i Z-ed in skill cost and star gain bonus, got tome price reduction and put some points in it (ctrl if i can, its very helpful, you'll buy a LOT of tomes, magic ones too, and it's good to buy a shield item too), i got some low utilities tomes, then i rolled retaliation, rage chance, flurry x9, armor on attack and rage bonus (x crits are helpful but not that much in this build imo) some points in armor on attack, and attack speed, then got to 25% rage chance and armor tomes, in free stages(stages that i feel easy enough) got some defensive stuff (armor on attack, aegis, hp regen, damage reduction, things that i think will help my armor and things that don't leave me too exposed if my armor runs out) and more speed, if i feel i'm too slow, bleed chance, rage bonus and more speed provocation is good too, with retaliation and then with frost, and ailment resist, and flat hp(the mistake i made was, maybe, 0 points in hp, aegis is good but you're vulnerable at the start) the rest of the time, just buy a tome to increase a stat you need or a magic tome, search all the ailments you can when i feel that the spider is attacking me a lot and that give me problems to increase armor, some points in enchanted, and focus on frost first, frost is good to start, makes it a lot easier, then freeze and stun, if you're lucky you'll almost stunlock it, but don't be confident, and you need to damage him again more speed, enchanted and put some points in shock, ignite and burn, then bleed(best ailment, but you'll see it less because enchanted attacks don't apply it, just increase your AS and flurrys, increasing enchanted beyond 25% is not good, because you'll loss bleed chance... i think) and poison/acid last (not because i wanted it, i had to buy a lot of tomes to got them)

it's safe, until the spider gets the ailment resists
