Drain abilities are not affected by the 175% efficiency cap and benefit from having both Streamline and Fleeting Expertise fully ranked.Īctually to clarify how this works: Because Fleeting Expertise also reduces duration you won't reach the maximum energy cost reduction by using Streamline and Fleeting Expertise, but maxing it will still reduce your energy drain because the efficiency it gives weights more than the duration you lose by using it. You ll also want the duration increase to make Radial Howl last longer.

You can just add some + duration mods to counter it though. This will reduce the cost of your Radial Howl to the minimum but, because of the duration loss, won't reduce Exalted Blade to the minimum. Originally posted by Handoiron:Exalted Blade energy drain per second is also affected by duration mods. This will limit the effect to your duration from Fleeting Expertise to -50% as well. A typical combination to hit exactly 75% efficiency is to leave both 1 rank from max for +25% and +50% for the 75% total. Streamline is 5% efficiency per rank to a max of 30% and Fleeting Expertise is 10% per rank to a max of 60%. This requires a combiation of both Streamline and Fleeting Expertise to achieve. The lowest you can get radial howl cost down to is 12.5. You still lose energy at the same tick length but the overall effect is to lower the cost per second.Įven though + efficience and + duration both affect channeled ability energy cost, the maximum effect is still 25% of the base energy cost. The limit to energy cost reduction is 25% of base so +75% efficiency caps your energy reduction.įor channeled abilities like Exalted Blade, duration also lowers energy cost per second by increasing the effective duration of the cost ticks. Exalted Blade energy drain per second is also affected by duration mods.
