What’s the point of Resource Cost Reduction stats on Rod of Kepe builds?
Not to be confused with Resource Generation, which I understand if you get that to 100%, combined with Ring of the Midnight Sun (with a 50% roll) will give you 100% uptime on Rod of Kepe’s effect by spending/refunding max resource every hit.
But I see on build guides call outs for ring of the starless sky (specifically mentioning its 50% cost reduction in addition to the damage) and tempers for Reduced Resource Cost.
If the ring of midnight sun is already refunding all of your vigor regardless of how much you spend, what exactly is the cost reduction doing? And if I’m spending 100% of my vigor, regardless of what the skill “costs”, what is being reduced?
My only guess:
Is it effectively making it seem like you’re spending way more vigor on each attack so Rod of Kepe is doing a much bigger crit multiplier? (For example, if I have 100 vigor, 20% resource cost reduction, and attack, it spends all 100 vigor, but maybe it acts as if I actually spent 100/0.8=125 vigor, when multiplying Rod’s vigor multiplier effect. So even though my max vigor is 100, I get 25 extra vigor worth to multiply Rod’s effect with? (the 0.8 above = 20% reduced cost))
Thanks in advance !
