That\'s nice, but it should be something like, after asking help from a hero:
Imbue your equipment with the powers of your god (Insane damage boost; devistating magical spells)
Imbue yourself with the powers of your god (Super-strength; super speed; super magical powers)
Ask for the god\'s assistance (Lightning bolt from the sky!)
And why does it have to be \"just creatures\"?
What about asking to
borrow a peice or two of your gods armor collection/weapon collection/book collection/alchemy kit?

Of course, a god has no time to give you the stuff directly, so you\'d need a hero to send the stuff to you.
[as well, there should only be so-many heros. like, 20 per god each with their own ability, and you get one at random with getting one in favor of your situation (if you\'re low on health you\'re more likely to borrow a healing hero then one that can kill masses of enemies) and only ONE of the heros can ever be summoned at a time; if all the heros are busy, then no hero can come to your aid, though one will be notified and will respond ASAP.
\"I must go now, you no longer need me.\" could be something the hero could say if he\'s needed elsewhere.
Same thing goes for the god\'s pets; there are only so many of them.
This way, you dont get 100 uber mages all summoning the same hero in one big battle all at the same time, looking increadably stupid, all the while.]
