There are hundreds of posts regarding instant cast.
worry  about equips first:

aoa +3dex (or get vespers for mid and upper gear totalling 8 dex)
rocker card in armor +1dex
two drops cards in survivor's rod +4dex
2 x orlean gloves slotted with zeroms (8dex)

get blessing +10dex
+10 dex food
=36dex+10 from high wiz bonuses ~ 150

ENGLISH:
Survivor's [2]? It can have only 1 slot, but with drops card it stills give you that amount of DEX (+4 DEX). Real problem is not how to have 150 DEX, real problem is having 150 DEX and nice MATK and Status Resistece. I still prefer having 135~141 DEX and use Feather Beret and Marc for WoE for example. As i´ve said, you still need MS in order to do a real good job like an instant caster.

SPANISH:
Sirvivor's [2]? Solo puede tener un slot, pero aun asi con drops da la cantidad de DEX que tu dijiste (+4 DEX). El verdadero problema no es llegar a 150 DEX sino llegar a eso y aun asi conseguir buen MATK y resistencia a estados alterados. Yo aun prefiero tener 135~141 DEX y usar Feather Beret y Marc para WoE por ejemplo. Como dije antes, aun necesitas de MS para hacer un buen trabajo como Instant Caster.
