I wondered if dexterity affects everything by making it execute/happen faster such as:

 

1 attacks

 

2 talents

 

3 spells (druid, wizard, priest, invocations, cipher spells)

 

Ok those I think probably but thought of some others:

 

4 Chanter chanting speed?

 

5 Potions?

 

6 Scrolls?

 

7 Items that summon things

 

8 Items/abilities that buff (like disciplined barrage etc)

 

9 Any other ideas or exceptions?

I am pretty sure dex affects all attack, recovery, and reload speed. Here is speed calculator maxquest made i think. Chanter chant speed is not affected by Dex its passive and its only affected by the chanter modal brisk recitation.

DEX affects action time (animation time) and recovery time. It's the only thing in PoE that influences action time. All other speed buffs in the game "only" affect recovery time.

DEX does not affect chanter “phrases” but it dies affect casting of invocations.

 

All quick slot item use is also affected (scrolls, potions etc).

 

Stuff like disciplined barrage, arcane veil etc is “instant” and so not affected by DEX. The only impact DEX would have is on the recovery before you trigger these abilities (you have to be out of recovery before these abilities can be triggered)

In other words, max Dex, meh all else xD.
