Fel Intellect

Fel Intellect was a warlock talent which improved a summoned minion's intellect, and the warlock's own mana pool.

Tips
This can be particularly useful when up against several mobs or a high level NPC, or in a PvP situation, where your opponent or opponents take longer to kill.

This talent is a must-have if you plan to take Dark Pact (old) and use either your Imp or Felhunter as a mana battery for raids or PvP. The extra mana might not seem like much but it can mean the difference between being caught short and having just enough mana to launch that last Shadow Bolt.
