There is no cool down between applications of frenzy, the skill is always ready for use. Its a very low mana skill (3 mana). Requires only 3 skills in total to become fully functionally synergised. Also if your mana is fully depleted from a mana burn then a barbarian will automatically resort to a normal attack so you can still leech life(safety +1).
