? Repeatable Quest: If the target of Psionic Lash dies within 2 seconds of being hit, Tosh permanently gains 50 maximum mana.
though, personally, i think that his Energy resource should have another use
for example, the more energy he has, the longer the duration of his abilities last (10 energy = 5%, up to an increased 50% duration on each of his abilities)
If he has 100 Energy, then Mind Bomb's duration lasts 6 seconds, and the stun is increased to 1.5 seconds.
though, it might make the need for his abilities to also cost Energy
not sure, just thought that energy should have another use than only being used for cloak
What about his combat stats like Health, Mana etc.
Its a really cool concept :D

As for his health, that's one of those stats that I'm not really comfortable messing with. For a hero like this, I'd recommend somewhere between 1400 to 1700, but correctly gauging the ideal maximum health for a hero is difficult without playtesting.
Thanks for the comment!
