Restrict casting to a unit with mana

[Damage]

Mana Burn is a spell which restricts casting on units that do not have mana - for obvious reasons.

How do I apply this same restriction to a spell which is NOT Mana Burn?

Base it on Mana Burn and trigger the spell?

sry misssunderstodd what you where saying

base it on mana burn

or order the unit to stop when it starts casting a spell on a unit without mana+error msg

@ above: sucks because its better with the Bloodmages Siphon Mana and set duration to zero and mana steal to 0.01

actully thats the only way to make custom restriction.

but if you dont need a custom restriction? its way better without

A custom restriction isn't going to work, as the spell will be cast by AI units as well, so it has to be inbuilt to stop them casting it all together.

Have to say I didn't consider Siphon Mana, so thanks for that.

Reason I wanted something that is NOT Mana Burn is because even if you set it to drain 0 mana, you see a "-0" appear when you cast it, which looks unsightly.

Anyways, solved now.
