Vetiki  

The trash surrounding Vetiki can be pulled without agroing Vetiki, and if you clear a hole, you can pull Vetiki without agroing his trash.

Vetiki hits anywhere from 100 to 5000, flurries, and has low attack. He is partially slowable, and is relatively easy to slow.

At 90%, 80%, 50%, 35%, and 20% he will 'split' int successively fewer mirror images (starting with 7 Vetikis at 90, down to 3 at 20). He will preface this with an emote 'Vetiki begins to cast a spell.'

Each split has roughly 100K health, hits for about half the strength of the main Vetiki, flurry, and remain easily slowable. There is no limit to splits that can be up, however each split's health is reduced by the percentage done to Vetiki himself (for instance, at 90% the adds all have 90K health. At 20%, they have 20K).

Vetiki himself has around 700K health.
