He can be "overcharged" with "help" from either tirek's magic absorb ability or… perhaps, dark energy fields.
When "overcharged", Windstar emits an electrifed blue bolts around him and colour of his aura, pupils and halo emits same colour as those bolts rather than their original ones.
He would also gain ability to grab and launch heavier objects(and other magic balls?) toward enemies of a very high force and velocity. His significant enhancement, also behaves as weakspot, is ability to manipulate organic objects. any living things punted by him will be instant-killed regardless of any magic defensives, while retaining charges that can shock and disable magics of enemies if struck by their bodies. If grabbed by him, they will be likewise killed instantly (mostly due to organs being destoryed in progress), Unless he lowers the charge.
As a side-effect, he must keep his magic aura on, as an overcharged magic spell can result an instability in his body, and killing him in the progress. Another problem is that it vaporizes almost everything dropped by victims, prevents him from looting.
One more thing, Range is decreased rather than being increased while charging his magic beam, although he's no longer need to shoot magic beams after a long charge.
