I've read through Mercurio's character sheet, as it is currently.

As it is, even if the history-section was complete, I'm afraid I couldn't accept the character. While I have no doubts you would roll fairly in the department of dice rolls, the main issue is that many of his effects are [i]forced[/i] onto other characters, or appear to be auto-hits or otherwise unavoidable. This is always a big no-no for me when I do roleplays, as I'm a firm believer that [i](unless the GM tells you otherwise)[/i] you should always have the ability or option to determine the outcome of another player's inter/action towards your own character. Having effects and spells that force themselves onto others, without them having a say, isn't going to fly with me.

In addition, while he seems amusing on paper, I question the viability and likelihood of the other characters in the group picking up someone who seems so clearly deranged or mentally unstable. While I'm sure you could score sympathy-points for him with Serafaye and Yinha, pragmatists like Aretemisia, Locke and Kaze seem very unlikely to want to travel along someone who teeters to himself and talks to invisible friends or hallucinations. He also comes across as flippant and unreliable, which makes me wonder why he'd bother to stick around with a group of random people when he has no apparent goals or ideals that align with the rest of the group.

Finally, his ability to manipulate and store 'karma'' is sadly just way too overpowered. Being able to essentially stockpile "luck" or "good fortune" in exchange for misfortune, which could be basically anything 'bad', is a rather absurd power to have. Say he stubs his toe while walking. +1 Karma Point. Say he gets a bucket of water thrown at him. +1 Karma Point. Say a fly lands on his pie. +1 Karma Point. Say an enemy insults him before a battle, charges him even though there are other targets available, and delivers a blow that causes a shallow cut. +3 Karma Points. Essentially, it would be incredibly easy to break and abuse the system, and many of his spells and abilities that are linked to this power are also just as guilty of forcing their effectrs on others [i]if[/i] they activate.

These are of course only my thoughts from reading your sheet as it is. If you feel I've made an unfair judgement, or misunderstood or otherwise failed to properly grasp your concept, please feel free to counter my concerns. I'm never going to just flatly forbid a character - unless they're broken as duck - and will always allow their creator to try and alleviate any issues I may have. :)

But, as for right this moment, Mercurio is not accepted.
