The Tavern

I'm not sure I've ever quaffed a potion of brilliance, even on conjurer types. I just don't come across situations in which it would be useful.

Is it just used to temporarily cast spells that are slightly out of reach? I could also see it seeing being used to counteract int draining when restore abilities isn't available. Any creative uses?

I also rarely remember to use might and agility but those have obvious uses and are quite strong.

It makes your spells a lot more powerful and reliable. Also, you could learn spells early.

Huh, I was under the impression that it only boosted int. Good to know.

I'll give it a shot on the GrEE I'm playing right now.

yeah id say the most powerful use for them is to be able to learn a spell you otherwise wouldnt be able to. but theyre great for a quick boost of spellpower too, kinda like might for your magical abilities

um the spellpower boost is very noticeable

think of it as a potion of might for conjurations

It's invaluable sometimes, today I was attacked by Nessos and had to quaff a potion of brilliance to get Bolt of Fire from 8% (yellow) to 1% (gray). Who knows whether I would survive without the potion, I had neither rF+ nor rPois.

Brilliance's impact on spell success rates is good, but the real strength of the potion is in the large spellpower boost it gives you, which increases damage/accuracy on conjurations and chance of success on hexes.

Cant imagine why it would be considered useful for learning spells, given that if you cant memorize the spell without the potion, you certainly arent going to be casting it reliably, if at all once the potion wears off.

Sometimes that 100% failure spell is the only one you've encountered which uses the skill needed to train it.

For example once in a blue moon, Haste is the first charm spell I use/encounter. In that circumstance, using brilliance allows you to memorize the spell so you can start training it so you can use it.

More frequently it's useful for the bonus spellpower. Seriously, like might for spells.

I have used !brilliance to get LRD usable on a character that had little magic training (at that point) in order to bust open one of those partly transparent stone cages with a glowing triple sword inside.

But, as others have said, the main reason to use them is for anyone who will like the spell power boost. You should quaff them for tough fights before using spells for which spell power matters, typically conjurations or hexes.

I tend to let them pile up until I really need them....

You can use them to get lv 9 spells up and running fairly early. Just the boost you may need to get shatter or fire/ice storm castable for stair hopping on V5. If I have enough of these potions I can normally clear Vault 5 as soon as I find it (or die horridly). Just an idea.

1) Memorizing a spell that is at 100% failrate but don't have the respective school open yet or any other lower level spell that can unlock said school.
2) Killing Cerebov
