[Dace De'Briago]

Simulcrum produces a clone at approx 60% of the casters level, which reduces the number of spells he is able to cast, as well as his fighting ability.

You can cast restoration on a simulcrum to restore the lost levels.

However, project image allows you to a) circumvent the summons limit and b) cast all spells at no 'cost' to you while the original character is uninjured...

So if you hide your character away somewhere sensible and/or make him invisible...
