Ammo System? {how to make it mana-based?}

[RainbowJamz]

So I'm making a modern warfare map and I wanted an ammo system, here's what I had in mind, and tried: Units have 25 mana, it does not regenerate and must be refilled using ammo crates based off mana potions. Their regular attacks don't work and they can only fight using an automatic spell based off Searing Arrows which would deplete 1 mana everytime they hit an enemy unit, although here is where it goes wrong. If I take away their regular attacks, they can't use searing arrows, and if I leave the attack with no targets allowed, the unit can fight without the spell (Searing Arrows) nonetheless. Is there any ammo system simpler than this or how do I fix this? All help would be greatly appreciated.

so, make them use searing arrows using triggers...

a way to do this is to pick random units within AOE of the unit then make a condition if its an enemy, then fire searing arrows...I have a similar system like this in my Fog Horror map, see if that's what you need and Im updating it with AI's...

Ok, thank you! I'll check out your fog map, do I have your permission to copy the ammo trigger you have?

EDIT: I can seem to open your map so would you be so kind as to post a screenshot of that trigger? I'm new to mapmaking. Thank you so much.
