When dropped, the attack rewinds 10 seconds. So you can make the same mistakes twice ;)
Seriously, maybe 5 seconds back in time. So upgrades are possible to 10, 12, 15 seconds.
Of course this is a dark elixir spell, and it takes up 2 or maybe 3 slots.
Attack time is NOT affected. So use this spell wisely (you'll run out of time quickly).
*ugh, only AFTER posting I get these "similar suggestions". This one is telling exactly the same thing...*
