Well, ok Charmille. But... then... how do tyrants spit fire? Is it some special Orc-Tobbacco that they chew? :-P
I mean... it might not be classified as a nuke... but then... how can you define these attacks from a strictly... non-magical viewpoint?
Melee far attacks? Throwing fire with a hand-catapult? It looks quite magical to me. The orc does a beautifull jump, then spits fire. Wow, pure magic! :-D
Force Blaster, Force Storm, Force Burst... sort of magicky tricks. I mean, how can you AOE without magic? Maybe like the Byzantine empire with the help of... liquid fire (igro pir). :-)
They're physical ranged skills. Tyrants/Destros dont have magic skills. They dont need spellbooks to learn their skills nor are they affected by Silence, Emp, Concentration etc. in any way.
As to how they do it, it is one of those secrets all martial arts have.
It's a bit like Tekken, or similar older video games. With the correct juggling of the keys... physical power transforms into some kind of unknown force. Yi-ha! :-D
