Bug: grimoire cooldown reduction doesn't work on spells you know from the ability tree?

[thelee]

I have Boethel's Grimoire at +3. I have skilled 1 point into Arcane Veil.

Both Arcane Veil and Blizzard have 15s cooldown. From the grimoire, I should get a -15% discount on cooldown, so around 13s.

When I cast Blizzard (from the grimoire), when the effect ends I get a countdown that starts at ~13s.

When I cast Arcane Veil (from the grimoire not from the radial), when the effect ends I get a cooldown that starts at 15s.

The only difference is that I have a skill point in Arcane Veil and know it independently compared to Blizzard, which I only know through the grimoire.

ACTUALLY, something else is going on. I bought a grimoire to test with, and all the cooldowns seemed to work with learned spells. I went back to Boethel's, and now Arcane Veil (cast from grimoire) is working just fine with reduced cooldown. Maybe it was some transient glitch that was solved by re-equipping grimoires or swapping loadouts? No idea. disregard

OK, i think i can more precisely describe what's going on.

1. Switch to a loadout grimoire that contains a spell you have an ability point in (in my case I tested with both Arcane Veil and Blizzard each with one ability point).

2. Cast the spell from your grimoire.

3. Note the cooldown of the spell when it finishes, it should have a cooldown reduction.

4. Now cast the same spell from your radial.

5. The spell "remembers" the cooldown duration reduction of the grimoire copy and has a reduced cooldown.

Now, try it slightly different:

1. Switch to a loadout with a grimoire as above.

2. Cast the spell from your radial.

3. Note the cooldown of the spell when it finishes, it does not have any cooldown reduction.

4. Now cast the same spell from your grimoire.

5. The spell "remembers" that there was no cooldown reduction from your earlier cast, and the grimoire cooldown bonus is not applied to the grimoire cast. No matter if you keep casting from your grimoire from here on out, you get no cooldown reduction bonus. You have to re-equip or switch loadouts to reset this.

 

This only affects grimoire cooldown. Essence cost reduction appears to work correctly (it correctly applies always to grimoire casts, and correctly never applies to radial casts). Switching loadouts to a different or no grimoire and back again "resets" whatever the game "remembers" the cooldown reduction should be.
