at what point is accuracy evaluated?

[demeisen]

Consider this sequence of events:

 

1. Char A: Starts casting an accuracy buff

2. Char B: Starts casting a spell

3. Char A: Accuracy buff fires

4. Char B: Spell fires

 

For character B's spell, is the accuracy for the attack evaluated when he starts to cast the spell at point 2, or when the spell fires at point 4?  I'm going to guess point 4, but that's purely speculation on my part.

5. Char B: Spell impacts 

 

Attacks (magical or otherwise) determine their damage and hit roll on impact. Thus, if my Wizard gets hit by an accuracy buff (or debuff) with a Fireball in mid air, this will affect the attack rolls when the Fireball explodes. Which for a spell like Fireball is admittedly a fairly small window, but it can certainly matter for intermittant effects like Chill Fog or Ray of Fire, or slow-moving projectiles like Rolling Flame.

Cool, thanks.  I had mostly been thinking of instant effects, but that makes more sense as a general answer.

Yup. This has an interesting interaction with Devotions For the Faithful, which actually buffs its own accuracy (for the debuff effect) when the priest is in the AoE.
