I noticed that my mage never gets a critical hit when wielding weapons that only do elemental damage, e.g. the Tesla Emitter or the Rod of Incineration. He's level 25 so I took him to kill a ton of scrubs to make sure. As soon as I switched to a weapon that does at least some normal damage, e.g. the Branch of the Holy Tree or the Wand of Power, I started getting crits at the expected rate. Has anyone else had this problem? I assume it is a bug, otherwise the critical rate of the elemental-only weapons would be zero. I am playing the Android version.
