Attribute Requirements for Skills feel too hard to attain

I'm playing Acolyte of Chayula. The build I've planned out to make things work, staying in theme, affords me only 145 attribute points to distribute.

A key skill for the class is Hand of Chayula which uses curses and marks.

The gear and skills the monk uses requires a split of Dex and Int.

Curses use pure Int. Marks use pure Dex.

Lvl 20 pure skills require 205 of an attribute from what I've been able to find out.

Even if I only focus on curses, which I'm doing with Whispers of Doom, it's not possible for me to reach those amounts. I'm not even certain I can keep up with my quarterstaffs and Eva/ES gears.

I could roll attributes on gear, use attribute amulets, or use lower level curses inline with the base Int requirements of my gear.

These options do appear in line with this style of game. But the values to hit still feel too high where I am right now and it concerns me in relation to the viability of my desired build. Not due to it not working, but due to the fact that I simply can't afford it even when I'm trying not to be outlandish.

I feel very constricted right now, and not in a pleasing way where I feel I can simply make calculated sacrifices.

I would like to see these attribute requirements reduced to be more in tune with the average attribute amounts of a standard build in a class's starting section of the tree.
