Hmm, I have two ideas:

1.) Lucas' power can only affect objects in sensory range; an exception to this are portals, but even then, he can only travel to a place whose image he has seen.

2.) Lucas' powers cause Brain Damage to himself when overused. This is further aggravated by his 'Concentration Pills'.

Just dropping my two cents in here. I tend to be sort of wary of powers that can 'overheat' or damage the user when overused because, and let's be honest with ourselves here, you're not going to decide your character's used his powers too much and turn him into a vegetable. No, it'll just be something brought up occasionally for drama, while your character sweats and strains and gives himself nosebleeds as he wanders merrily around being... well, omnipotent. It's not just you, nobody ever makes the 'power overheat' matter in things like this. It's only ever a talking point.

But, hey, I don't work here. GMs get the final say, I just thought I'd mention that. If the GMs say that'll work, that'll work.
