Hello,
I find some people in trading who propose her fana / cursed hephastos.
How can we give our bin demon to another warlock ?

You can't. Those Demon sellers have found certain kind of Hephasto and they're selling you the game where you go bind it yourself.

ok i see thanks

does a demon bound in norm has same stats as the hell version or do I need to bind in hell?

Bind in hell for higher stats

A thorns cursed extra fast spreads curse superwell and is epic vs bosses.

All my good ones has been consumed by mistake xD
Had a near immortal thorns, amp, extra fast mauler. Theese guys has stun/frenzy/crushing blow on top, but consumed by mistake xd he was also physical immune or stoneskin or something.
