Nasty spell problem

Hi all,

I've got this spell problem for wc3 TFT. I based this spell off of Doom spell, and made it have 10 levels. Now, when I start the game I try to cast it at spell level 1 and it works on all creeps below level 6. But when I upgrade it to level 2 or more, the spell says "The target is too powerful" no matter what level the creep is. I couldn't find any options in editor to change that - the only thing I can change is what I can target; enemies or allies... etc. Also, I want it to work on all creeps from level 1 to unlimited

Second problem is a spell based off of Life drain (dark ranger spell). In editor I allowed it to target allied units, but in game I can only target enemies. There's something wrong here and I cannot change it.

Does anyone have any ideas?

Check if all tags say lvl6, and all target tags say (enemy, non-hero, ground), etc. Those tags should be the same on all 10 levels of them.

I tried that, but there's no such option. At least not in editor.

Targets allowed are "enemies, non-hero" on all 10 levels though.

And for Life Drain spell targets allowed are "Allied".
