Ah! Clever idea, Hyro. I sense Rage-Quit potential! Aside from thematic design, why not have pillars switch to generating their opposing element?
In my opinion the sheer concept of Pendulums always screamed
Time to me. Towers and Pillars could probably be
Earth turf... though I had an idea about combining a cool
Air card with Pillars/Towers.
I've had this idea for a long time now, and was hesitant to post it due to lack of art... T_T
But alas, I think this at least gets its point across. Thematically, I think Clockworker should stay as is, with pendula.
