Just going to echo Wayward here. Starting out with complete immunity to two of the most common magical elements is simply too powerful. However, having them start out as small resistances and develop from there would be fine. I'm also a bit wary of Fireball and Ice Spike. These are obviously meant to be more devastating versions of [i]Fire[/i] and [i]Blizzard[/i]... which would be fine if we didn't state explicitly in the OP that spells should stay to the tier one level at the start of the RP. Again, those are things that your character is more than welcome to learn over time, but starting out with them is excessive. 

Lastly, overlimit is a little strong. At a base level doubling your power (ala D-Mode and L-Mode of Kengo and Kotaro respectively) is fine, though even doubling the power has a backlash in Kotaro's case (for Kengo I assume it's more along the lines of a 1.5x power boost, though I could be incorrect). However, right off the bat being able to triple or quadruple your character's power, even "at risk" of his own life (which I've seen many RPers use and not take even a bit seriously, not saying you would, but I'm just wary), seems a bit strong. Again, maybe this level of overlimit could be developed over time?

The main idea is we want you to be around the same level of power as the other apprentices, especially the ones on your side, and we want you to have room to grow. Look at Matilda and Kengo. Both have very moderate ability lists. By comparison, your character dwarfs them in terms of power. Please consider rectifying our concerns in order to be accepted into this RP.
