What's to expect on POE 1.0.6

1.0.6 has a summoning theme and contains:

Four new skills, all useful to summoners. One of them is a new type of (short-lived) minion, and the other three are utility skills.
Various adjustments to the progression of other summoning skills.
Two new skull-themed cosmetic microtransactions.
Two new achievements.
Four new Unique items.
New vendor recipes.
Hopefully the ability to test some PvP tournaments (if it's not ready sooner).

We estimate that we'll be deploying 1.0.6 on around January 29, NZ time.
