biggest tip to mana builds (imo) is to always have cleansing wand or regen wand to counter poison and for archer builds is to get massive block and/or a lot of buffs to arrows (my fav setups are bombstone, dumbell, glass bottle, archer's wand for massive bow damage for mana, or shield spirit, stopwatch, hercule pavise x2 or more, and some pretty anklets for MASSIVE block on turns 2+... only tried the first setup as of rn tho)
