Explanation of talent stacking: If you have taken Spellsteal talents at 1 and 7, succesfully procing both of these would cause the enemy hero hit to have their ability power reduced by 70%
The level 13 talent tier is unique in that it has 5 options available - 2 of these options, however, are only available if you have taken certain other talents.

Because of the intricacies that this ability naturally holds, standards must be established for what can and cannot harm the hero made "neutral".

AoE attacks will hurt the neutral hero, regardless of team that they originate from.
Skillshots will hit the neutral hero regardless of team that they originate from.
"Naturally" Cleaving attacks(Zarya basic attack, Greymane 20 basic attack upgrades) will damage the hero, as they function similarly to AoE abilities.
Basic attacks can only be targeted on the neutral hero if they are from the team the hero is normally an enemy of.
Auto-targeting damaging abilities will not automatically target the neutral hero if the hero using the automatic targeting ability is a normally friendly hero(Li Li can't blind a neutral ally, PTR Tassadar's 20 basic attack upgrade can't jump to a neutral ally, Zarya's Gain Train will only give neutral allies a shield, ect)
Experience granted from a neutral hero death functions as though the hero is not neutral.
Towers will not target a neutral hero, even if they are normally an opponent of the hero.
Minions & Captured mercenaries will not target a neutral hero, even if they are normally an opponent of the hero.
A neutral hero cannot contest mercenary captures, watchtower vision, or anything that is contested by his body presence.
A neutral hero can channel objectives, and they will be properly assigned to his standard team.
Any placed buffs or debuffs will apply to the hero - regardless of which team they originate from. This means an enemy Tyrael's Sanctification will apply to a neutral hero, or a Rehgar Earthbind Totem will slow them.
The hero themselves abilities function normally - If they activate Bloodlust, it will only apply to their allies, if they place a Sanctification, it will only grant invulnerability to their allies.

Purify & Spellsteal can "steal" most debuffs & buffs, but certain abilities must be exempt due to their function.

Anything variant in duration or placed cannot be stolen - this means you can't steal a Moshpit stun, a Sanctification Invulnerability, Butcher's Lamb to the Slaughter debuff, Butcher charge unstoppable, Rehgar Earthbind totem slow. All of these are one of the above categories - Butcher charge is a variant duration unstoppable, All the others are a placed area debuff. This means that most vision debuffs cannot be stolen, as they are area reveals.
