Millz, the idea is that the troll hero inspires balance in his allies. Making them harder targets (devotion's defense +) and also gives them a chance to reduce the damage that is inflicted upon them.
If an enemy strikes them, and that damage is 20, and they proc the chance to reduce damage, then the damage might only be 15.
But did you want a physical type aura? Or magic? Or something in between? Like some blood drinking vampiric effects?
You could power up the aura with an ability, like some kind of SHOUT. For example, modify a howl of terror, add some minor damage, and set a timer to start when howl of terror is activated, to increase the damage reduction on your aura'd allies. So maybe 75% damage reduction instead.
It gives attackspeed based upon how many units are around the Troll.
Lets say the troll walks with 5 creeps, and the aura gains 3% attackspeed per unit, it would be: 3*5 = 15% increased attackspeed to all units nearby/including the troll.
Actually sounds like a pretty original idea, I've never seen one.
If you find it in the Object Editor then post its name here
Spiritual Aid
An aura that gives nearby allied units ability to heal themselves every time they cast a spell by 50%/60%/70%/80% of spell's mana cost. Also, every time Troll Mage casts a spell, he will heal nearby allies by 50% of spell's mana cost (optional).
nice but how to trigger it...also only use GUI..how to detect when a ally unit in x range of him casts a spell?
is there a better way to change the amount of hp healed i dont wana use by % of manna used
that could be unbalanced
my map has alot of casters with auto cast spells witch e.g shammy(bloodust)
EDIT:got another suggestion that 1 was realy good intill i rememberd all the casters with auto cast spells they would like never die and could course some lag so get where im coming?
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
