You ask the same questions @Leo Jason Caris once did with the only difference Lion asked about Metapotence and Absolute Will. Essentially, that is not important how users, they simply do it. You know, when you move your body, you simply move it and there's no need to clarify if you did by thinking, wanting/wishing, willing/deciding to do so. Because Leo got really into it and asked if it is hard to will and for that question I quit answering. You ask too specific questions this wiki isn't supposed to respond.

Nonetheless, Logic Defiance is the power to ignore rules of logic and do seemingly impossible feats by braking logic solely. For instance, its users could draw a square circle, lift an object so heavy that they can't lift it and overall defy rational sense. This power is only matched by Paradox Manipulation, Principal Manipulation and enormously powerful Axiom Manipulation.

@Clara Sirius I apologise for all the strain my questions brought upon you. Ever since we spoke about that my head has been focused on other aspects of powers instead of the actual functioning. Thank you for opening my eyes. ^^

@Primus1662 In simple terms, yes Logic Defiance allows you to achieve any effect by desiring it and the power automatically negates the logic that would oppose such an effect. No effort exerted due to the nature of this power. You just "do" the impossible just because.
