1. Put maxed mana capacitor and power of storms shards on the Abyss Lord (note you will not have full mana that way).
2. Proc the power of storms shard with the Abyss Lord's secondary attack (it won'f regenerate the mana that way unlike the primary attack).
3. Note the amount of mana gained.Expected Results: The power of storms shard should regenerate 60 mana like suggested by the tooltip (20mana/s * 3s = 60mana) or state the actual regeneration properly in the tooltip.
