Double check my salamander

Here's my revised creature

Did I misunderstand focus power? Since Arteseno is might 15 I started each power with a level 15 effect and I did not give him 2 mastery points per focus power for downgrading the effect from level 25 to level 15. (Otherwise the 2 mastery points he'd receive from having a focus power capped at level 15 rather than 25 could be used to by the level of the power back to 25).

Evasion is an optional rule, I used it anyway
