While my character was stunned, the player of Thunder (my opponent) graciously informed me that I was able to evade while under the effects of Loathsome Screech.
So I looked around and saw this wording on Stun Bolt.
"While Stunned, the victim may not commit any offensive actions, but may still defend as normal, including if they wish to activate defensive spells, evade or stumble away."
Hence, I started to wonder. Does this wording also apply to all spells that "Stun" ?
(eg Loathsome Screech, Fire Ball, Flame Thrower etc)
Since some of my other characters also have them and I should also let those subject to "Stun" know about this.
