Marks applied by Hand of Chayula cannot be re-applied after being consumed [not a bug]

There seems to be a relatively long period of time, when the enemy cannot be marked again after mark is being consumed. This is very limiting, given how weak the marks already are

it is a bug even if this behavior is intended, because is not described anywhere on them gems or any other place, and yes it is a big deal, basically like you would be hiding that a skill has a cooldown

Sniper's mark is only one with cooldown, is it what you're using?

yes you are right the cooldown is there, did not see it sorry
