As an ultimate I would think 10%/20%/30% is good. Maybe castable with a cooldown and nondispellable. Like cooldown is 40 seconds, lasts 25 seconds.

I think all that should effect heroes though, a tech with 50% spell reduction is going to be so hard to counter. Tech strategies are already really strong and the only offensive counter is aoe spells and you still get hexed/lassoed/netted if you are farming them aggressively. You can maul them too but only with avatar and you can even die with ava if they have a frost tower.

I don't think you have to worry about giving maulers "another op advantage". Mauling has its moments but it it can be weak compared to a tech +hex/lass/roots build or a pure hk build and frost towers really mess with mauling. There usually isn't more than one mauler in each game, if at all.

a set ulti aura is a nice idea, but for even MORE balance i like master-hero's idea of it being a roar instead of an aura. like the warlock's shout or something to that effect lol.

we all know one of the main ways people kill mass's of units is with spells. With 50% spell reduction, unit swarms would be too OP. and picture darks with 50% spell reduction lol.

very nice idea though i would like to see it put into effect.

Now that u mention a gold aura though.. that could be neat.. maybe something like any enemy within the aura of the hero gets you a small set amount of extra gold per kill when under the affect of the aura? idk something to that extent, keep in mind it would be a set value per lvl, it would be too much work to make the gold value based on the unit type that your killing.

Also for the idea i had i think i like the roar idea more also. Not only will it be easier to make happen than making a custom aura but it will also be more balanced in the fact that it can be dispellable and also limited with casting etc.. i think it should be something cool tho like a ulti and be semi strong, prob is tho if its too strong could be too good of a game ender maybe.
If someone got to lvl 16 a good amount ahead of other teams and got that to like 50% or something and rushed a base with that casted it could be pretty hard to counter those units.. but then again not so much because a jammy could dispel it and save the day.. xD
But an element of surprise attack with that would be quite affective..
Now if i did it this way would it be fair to have it also affect heros then too or no..
and this would be a great offensive way to counter those ppl that run shoot 2 waves and then ww away again, becuz this would allow those units to live through those waves now in your base if its casted.

Theres a good amount of approaches this could take. just gotta find the best one and most fair/balanced..

Sounds like it would be cool for the gold aura 2, it wouldn't matter if it's not different for different unit types.

I think the range should be pretty good for that damage spell reduction aura.

Lol. U mad?
Lol. He mad

pillage only works on buildings...

and the aura sounds cool except it should cap off at 30-40% 50% is already too op for maulers... i dunno but make it like 20%physical damage reduction and 30% spell damage reduction cuz in the end usually its the spells killing them (not many unit fights)
