[Blackrockorc]

i hope this is the right place to post this. but anyways when a unit(any unit or unit type) i want a gravethingy to appear. and when a certain item is used next to it it revives tht fallen unit. could someone come on wc n trigger tht into my map please.

jai jai i seen the triggers in tht sytem. the loop would wouldnt revive the trolls. im not sure if u member but all the trolls are normal units. tht loop will revive heros. if i set it to ground units then pretty much everythign tht dies will b reviable. imma dilly dally with things n come up with one.
