Corpseless version of Carrion Beetle (spell)

[ShadowSpawn]

It would save me a lot of time with trial and error trying to make it work with triggers, as it is for a Night Elf race rework and they have moving buildings. Please and thank you!

You can base your spell on Summon Water Elemental for example and then use a trigger that counts the number of summoned units and when that number becomes greater than 5 for example, make a trigger than kills a random unit of the type of summoned unit.

I really wanted to use Carrion Beetle because it could be autocast, had that limit already on it and also had a field where the summons would die with the caster, which is important in this case. Also the number of these units is a bit dynamic based on number of town halls and their level. Could that all be done with triggers?

The thing with autocast abilities is that they all need something to trigger them (i think?). Being next to an enemy/corpse/unit with buff
Do you want the summoning to be triggered all the time? or maybe when in a battle?
for the latter, i suppose you could use a dummy ability like Slow with autocast, have it do nothing by setting slows to 0% and duration to be really short. Then use a Trigger like 'A unit Casts an ability' with 'Ability Being cast = Carrion Beetle 2.0' condition and then just create units and set a maximum with triggers. The summoned units dying with the caster is easy to make with another trigger.
if you need specifics than say so and i will show you an image or something
