1) Is this a capped dDEX Rune Chopper build with Askar that overcaps Haste with Turban?
yes -> use Askar
no -> go to 2
2) Are you soloing?
yes -> use Askar
no -> go to 3
3) Is your accuracy above ~85%?
yes -> use Walahra Turban
no -> eat acc food and go to 4
4) Do you have any Haste buffs?
yes -> use Walahra Turban
no -> get them and use Walahra Turban
Askar for soloing because of the Defense and VIT more than anything else. It's not a huge difference but I've always preferred if for that specific application. Askar
can be superior if your accuracy sucks and you have no outside Haste buffs, but that really shouldn't be the case.
