new building tavern!!!

in the tavern free heroes come to rest and you can hire them for fight for you for a period time !!!.
tips : these heroes cannot upgraded
for hire heroes you must spend gold and exilir every day
max number of days you can have a hero is 7 days
you can only have a hero at one time
when you expel your hero ,your hero go away and you dont give any rescourse from it!!!
these hero dont get house space they are rest from tavern !!!
after the period time has expird you must wait 24 hours to next heroes be ready

if this is good idea plz rate

good luck
