- Knowledge is power.
Each rank has a minimum level limit for players that can receive the buff. If the target's level is too low to receive the rank cast on him, the highest rank possible will automatically be cast in its place.
According to the RPG, the spell requires a hair or dung sample from a fox to cast.
Tips and tactics
This spell used to be more expensive, but as of Patch 2.3.0, the mana cost of casting it has been reduced. The relatively long duration of this buff allows you to "stagger" your castings. Cast it on yourself, wait 5 minutes; cast on party member 2, wait 5 minutes; cast on party member 3, etc. With the new lower mana costs, the need to stagger this is greatly reduced, however this technique can be used to reduce the "downtime" associated with buffing the entire party at once.
Higher level mages (level 56+) can also use the spell to cast an equivalent effect on all party members at once. The duration of the Arcane Brilliance spell is 60 minutes, compared to 30 minutes for Arcane Intellect, Arcane Brilliance, however, uses more than twice as much mana and requires a reagent. The extra duration is a great help during long instances.
Intellect increases the rate at which you learn weapon skills. Should you have a friend who is practicing weapon skills, this will help out.
- Arcane Intellect is a basic Mage spell in Hearthstone. The flavor text reads: "Playing this card makes you SMARTER. And let's face it: we could all stand to be a little smarter."
- Patch 9.0.1 (2020-10-13): Now gives 5% bonus to Intellect (was 10%).
- Patch 8.0.1 (2018-07-17): Re-added.
- Patch 4.0.1 (2010-10-12): Removed.
- Patch 3.3.0 (2009-12-08): The buff will be stored in a Consolidation Box when received. It will come out when 3 min is left.
- Patch 2.3.0 (2007-11-13): Mana cost reduced.
- Patch 2.0.1 (2006-12-05): When casting a higher rank spell on a lower level friendly player it will automatically cast the highest possible rank of the spell. Previously, this had to be done with a macro that picked the proper rank based on the target's level.
- Patch 1.1.1 (2004-11-17): Reagent requirements have been removed.
- Patch 1.1.0 (2004-11-07): Ranks 4 and 5 now require reagents.
- Patch 0.10 (2004-09-18): INT boost decreased to offset the increased mana pool per INT point. (Effectiveness will remain the same.)
