Items that change attack-type/range

Hi i want to know if there is a item or ability for items(or just a normal ability) that can increase the range of a unit? and i also want to know if there is a item ability(or just a normal ability) that can change the attack type of a unit. Like instead of piercing it will do chaos damage when carrying the item:Hellbow(for an example)

IS THERE SUCH A SPELL? :(

i personally dont know specifically.

you could base it off of chaos, but that replace the unit completely etc.

Well... here is some questions:
1.there is a chaos grunt and a normal grunt.. if i give the grunt the ability chaos(grunt) will it then appear as a chaos grunt?

2.if i give for an example the archer the chaos ability(grunt) will it then appear as a chaos grunt?

3.if i create a chaos archer and gives a normal archer it the ability chaos(archer)<-custom! then will it become a chaos archer?

help me :\

Sure, you could do it that way.

Alternatively, you could set the second attack of each unit to a chaos attack that is otherwise identical to the first attack, and use upgrades to change which attack is used. Similarly, you can use an upgrade to change attack range, but only an upgrade. There are no abilities that do that.

The thing about using upgrades is that they apply to everything of yours on the map.

Well.. i think i have seen an item ability that enables attacks(first,second,both) but i need more than just two different. that i really want to know on how to do is:
hero aquire:
1.bow=gives ranged and piercing attack
2.sword=gives meele and normal attack
3.torch=gives meele and chaos attack

theese was just examples... i hope anybody can help me..

thanks anyway Panto.. i maybe can use your way ^_^
