Talk:High Spellscreen/@comment-4613046-20130815144510

I did some testing on this ability's duration and it's upgraded version yesterday. 100 tests were done; 25 tests based on canceling the spell once the buff was applied and 25 based on keeping the spell channeled until stamina bar ran dry. The other 50 tests were the same except using High Spellscreen.
 * Results vary from a couple of milliseconds.

Spellscreen takes roughly 3.1~ seconds to cast.

The buff that is applied lasts between 57.9 seconds to 59.0 seconds. Conclusively 58.6 seconds was the duration that came up the most often.
 * This is based on simply casting the spell and canceling it / starting the timer.

Spellscreen lasts for 58.6 seconds regardless on how long you hold it down for. Conclusively holding down the cast will not extend the duration of the ability nor will it refresh the ability like one would think.

High Spellscreen takes roughly 6.7~ seconds to cast. The difference between the two timers is 3.6 seconds which is longer than just the basic Spellscreen.

The buff that is applied lasts between 88.5 seconds to 88.9 seconds. Conclusively 88.7 seconds was the duration that came up the most often.
 * This is based on simply casting the spell and canceling it once it reached level 2 / starting the timer.
 * 88.7 seconds = 1 minute, 28 seconds, and 7 milliseconds

Like Spellscreen, High Spellscreen lasts for 88.7 seconds regardless on how long you hold it down for. Conclusively holding down the cast will not extend the duration of the ability nor will it refresh the ability much like its level 1 variation.

Conclusion: Is the extra 30.1 seconds duration worth the 6.7 second cast time?
 * Personal note: Not really.
