Introduction

FiveSec monitors your mana regeneration. It displays a bar — similar to the casting bar that shows when you cast a spell or use your hearthstone — when your mana regeneration is disabled. It is meant as an aid for casters to use their mana better.

Each spell you cast disables your mana regeneration for 5 seconds. If you are about to cast two spells - one with casting time and one instant — it is better to begin with the slow spell. Regeneration is active until the slow spell is completed, and the instant spell will only add a split second to the five you already got.
