Arcane Compendium entry Edit
You have decided that elemental attunement is more important than arcane knowledge. You can receive a boost to affinity gains in exchange for slower magic XP gain. This is a permanent effect.
This talent doubles the speed at which your affinity changes, but causes you to gain XP from using spells much more slowly.
One example is the Fling spell. This spell, without Affinity Gains Boost, will increase your air affinity by 0.05%. With the talent, however, you gain 0.1% air affinity. Affinity will still decrease if you use a spell of the opposite element. This decrease is also doubled if you take this talent.
Only get this if you know what you are doing, or if you are a high level. This effect is permanent if you go above 50% of any affinity.
