Being untargetable (Yi's Alpha Strike, Fizz's Playful/Trickster, Fiora's ult, etc.) prevents lots of bad things from happening to you, but does it stop everything such as:
- AoE effects
- Nunu's ult (damage and/or slow?)
- Morgana's ultimate (if untargetable, can she not start cast at all, or if already on, will it "break" the leashes?)
- DoT ticks
- Ignite
- Morde's ult
- the end of Vlad's ult
- Global spells
- Karthus's Requiem (ult)
- Twisted Fate's Destiny (ult)
Does "untargetable" mean literally that, that no targeted spells ("click-targeted" spells, skill-shots, or targeted AoEs work) land but non-targeted (point-blank AoE, global) do? (But still, what about DoTs…)
Best Answer
Untargetable refers to champions in a state where targeted spells cannot be cast on the untargetable champion, and nontargeted spells such as Karthus's Requiem will have no effect. Additionally, they cannot be targeted by auto attacks.
