Feat Testing Data
Per my testing, this Magical Feat may not work as expected. Casting Shadows at 25 mana took my mana down to 82% both before and after learning it. This might only work by using the actual HARNESS command. Additional testing required. --Endair 22:59, 19 January 2013 (UTC)
Before training Deep Attunement, I went from 0% to 100% in 4 mins, 31 seconds.
After training, I went from 0% to 100% in 3 mins, 48 seconds.
This represents an approximately 18.85% increase in mana regen speed.
Testing was done using a gath mysanda from charging until full mana message --Endair 22:29, 19 January 2013 (UTC)
I could learn the advanced symbiosis at ~300 arcana and scholarship.--Volcanus 5 June 2015
Dedicated Cambrinth Use
I can learn this feat at 91 attunement, 100 arcana. I don't think attunement is a requirement.
