That gets frustrating for sure. I have the same problem occasionally.
Happens to me ALL the time even at 120 Magery....should not happen at all with 120 imo but with 110 you should expect to fizzle sometimes.
Raise that evil and magery to 120. Should help alot
Happens to me too. As an elder mage think they should appear about 87% of time yet they fail two or three times in a row sometimes. Terrain seems to make a huge difference. Much harder to cast in wooded areas with line of sight often being an issue. Spell seems to be failing more now than it did before in open areas as well.
Note if you were cursed with feeble mind that can do it to. Sometimes it is easy to miss that when the action gets hot.
Ya they better adjust this for NL if there are no power scrolls. When I make a new mage toon for doing Shrine battles, I have to put their magery to 110. At 100 magery it takes so many tries that you rarely have 2 EVs out at once. Sometimes you dont even make one before the captain is dead. I had to use Blade Spirits at 100 Magery.
“Hello, you have 0% chance of fizzling energy vortex at 120 magery, even at 0 eval. It is possible your concentration was disturbed, or if you’re running in protection, being mana drained/vamped(to a level on mana below what is required) or paralysed after casting will have the same effect”-+-
