You can try doing episode about illusions, focused mainly on what does and what does not work on them. Just to raise awarness of pubbers that their builds are often supremely retarded.Episode could point out which passive skills are transfered to illusions (there are a few), wether illusions benefit from stats / raw damage / raw IAS / auras / orb effects / crits / evasion / cleave / maim, show a trick with illusions tanking roshan, I think I also recall someone suggesting myth about fatal bonds transfering vastly increased damage from illusions, some skills can one-shot illusions on sight (no, i'm not talking about obvious Stone Gaze and other purges), point out interactions of illusions with Transformation skills (again someone mentioned firefly illusions already)...
Will batrider's illusions have permanent firefly(not the flame but the ability to go thru cliffs and stuff like that) if you are using batriders firefly when you take illusion rune?- Looks really funny with scouting and stuff =)))
You can not take agro from creeps when u put attack on illusionsYou can use manta with courier if u have mana(from bloodstone or soul booster)... Useless but fun! Druids bear can use manta if he has mana(Bloodstone or soul booster).Voids illuisons can move and attack under chronosphere...Using manta with windrunner after using ulti on some1 her ulti continues if you don't change the target...Using manta with luna after using ulti the sentinel(at least I think it's called sentinel xD ) over her head dissapears so they can't tell by your ulti which one is not an illusion...(I think I've posted this already but nvm)
Mirror image (applies also to Manta Style) can dodge Thrall's Glimpse.
Razor will get bonus damage if he casts Static Link on enemy illusions.
If warlock uses fatal bonds on some1 and there are illusions in that bond you can deal greater dmg to the hero(es) by attacking illusions cause illusions recieve more dmg...
good one divide now I don't know if morphs ulti is considered as illusion(it can't attack rosh so I guess it can be)If morph copies alchemist he will have bonus gold income if alch has leveled goblins greed (a very good way to farm with morph as he is an item dependant hero)...Rikis illusions will deal dmg from backstab
Hmmm I think you have to last hit with alch but not 100% sure
Alchemists illusion has to get the last hit to make greed work
Kunkka's and Gondar's(can't remember if there are more) illusions dont have visual effects of their passives so you can easily see which is the real one...If naix enters an illusion enchnatress can dominate it and chen send it to the base xD
Axe's illusions will deal damage with counter helix.
