I forgot to mention something in the patch notes! The Summon Raging Spirit and Animate Weapon skills create a new type of entity:
flying monsters! Our skill coders describe flying monsters as:
"
1.0.6 introduces flying monsters to PoE. Flying monsters interact with terrain like projectiles, meaning they can fly over gaps and small blockages that ground-based enemies would need to path around. Flying monsters will not block the pathing of non-flying ones - they can walk under the fliers. Flying monsters are also immune to the effects of Burning ground, Chilled Ground, Shocked Ground and Tar. "Cloud" effects placed on the ground, such as Consecrated/Desecrated Ground and Poison Clouds will still affect flying monsters.
The minions summoned by the new Summon Raging Spirit skill and the Animate Weapon skill are flying monsters.
Needless to say, this will be used in the future on enemies also.
