Are you saying that whenever XX unit type gets to 50 mana they cast the spell?

Triggers

Test Map

Detect XX

• Detect XX
  • Events
    • Unit - A unit enters (Playable map area)
  • Conditions
    • (Unit-type of (Triggering unit)) Equal to XX
  • Actions
    • Set unit[(XX + (200 x 0))] = (Triggering unit)
    • Trigger - Add to XX Actions <gen> the event (Unit - unit[(XX + (50 x 0))]'s mana becomes Less than or equal to 50.00)
    • Set XX = (XX + 1)

XX Actions

• XX Actions
  • Events
  • Conditions
  • Actions
    • Custom script: set bj_wantDestroyGroup = true
    • Set RandomY = (Units in (Playable map area) matching ((Unit-type of (Matching unit)) Equal to Y))
    • Unit - Order (Triggering unit) to X (Random unit from RandomY)

Explanations

When a Footman(XX) cast Flame Strike which cause his Mana to be less than 50, the Footman(XX) will find random Gnolls(Y) and Firebolt(X) them.

Notes

- You should create the unit yourself via trigger instead of placing them in world editor because the triggers will only be triggered if the unit is entering the map.
- Remember to put the "X" spell to the "XX" unit or else the "XX" unit won't cast the spell that doesn't exist in his abilities.
