In my world a Magic High Nation is fighting against high tech level Nation about the same level as one of the nations in our world. I'm trying to decide what sort of enchantments can be placed on arrows to make them stand up to Modern military weapons.
Note : The conflict will be mainly a guerrilla war.
List of enchantments
Explosive Arrow. Explode on contact producing an explosion about the same as your average RPG.
Combustion Arrow. Causes organic material to spontaneously combust.
FaZe Arrow. Phases through all inorganic materials or anything that is dead.
Madness Arrow. Inflict enemies with Madness.
Multiplication Arrow. Multiply into at least seven arrows while in flight.
Hunter Arrow. Will follow the target anywhere and after launch, and will maintain its maximum speed until target is hit.
Lifeforce Steal Arrow. Takes the life force out of all targets killed by the arrow and transfers them to the archer, giving him an extra life for each enemy killed, and making him stronger and faster for a time.
Cold Arrow. Sucks all heat from any substance they pass through.
As a guerrilla general fighting for the magic side, I can only afford to choose two enchantments on my arrows. Which combination will best close the gap between me and my enemies' modern firearms?
More information in response to the comments: Most of the fighting will be in the wilderness which is mainly forest and mountains.
To establish a target, an archer must know the target's location. This doesn't necessarily mean he could just simply hear footsteps behind him and fire without even turning around.
And by sucking all the heat out, I mean just that I mean 0 degrees Kelvin.
