problems with passive abilitied for items

[Impac7]

I use items with many abilities. If 1 item has a casting ability everything's ok. However i want to make some items like:
(it is simple but i cant think of the way to fix it)

I make 1 plasma weapon. I use custom orb of fire for example to change the fireball with my missile. However even when using the data attack index : 2, if a paladin has this item he will attack from his real atatck range like ot can be 10 even if the ability is supposed to be 1000, seemingly the range of the passive doesnt work. I want to base the attack range on the item's ability. If 1 hero gets an item having an ability with high range (p.s searing arrows and autocast dont work on items) to attack with the high range even if it's real range is low.

If a hero with high range gets an item, the ability (lets say it;s 5 range) to make him attack close.

Suggestions for other abilities that can do that ?

You can use pheonix fire, however the ability wont mind the heros cooldown.

I think you can use barrage also.

I need the range, barrage and phoenox fire dont change the range. Also item fire bonus can activate the attack 2 with its range only if im targeting an air unit no matter i use only ground target. Whether you target a building or ground unit, the attack is still like attack 1.


I would GLADLY use triggers if i knew the action for changing the range. But there is only change acquisition range and that doesnt help. So do i miss triggers that can do that ?
