Looking good. The only problem is that the [i]'Incendiary Rounds'[/i] will be very weak for the opponents I'll be putting you up against. How about increasing the damage dealt so its based on Sigma's [color=red]Attack[/color] rating instead? Also I'm not going to be using probability-based abilities if I can avoid them, so the [i][b]'Burning'[/b][/i] status effect will definitely kick in, rather than just maybe kicking in.

If you make those changes the Ability could read as:[indent][b]Incendiary Rounds:[/b] [color=yellow][b]Cost 3[/b][/color]; Sigma prepares an explosive incendiary round. Its next attack will deal AoE heat damage equal to his [color=red]Attack[/color] and causes the [i][b]Burning[/b][/i] status effect. [b][i]Burning[/i][/b] causes damage equal to [sup]1[/sup]/[sub]2[/sub] Sigma's [color=red]Attack[/color] (rounded down) each round. [b][i]Burning[/i][/b] does not stack with itself.[/indent]

Are you sure you want to limit that to just Electrical damage, not more general Energy damage?
