My question is when you use the multiclass feat Sneak of Shadows for the 1/encounter sneak attack damage, does it increase by tier like the rogue class feature Sneak Attack, Heroic: 2d6, Paragon: 3d6; ...
I know they changed the way you multiclass to feat-based, but is there any way to start with two classes and level them both at the same time like the gestalt rules for dnd 3.5?
Is there a limit to the number of times you are able to multiclass, for example could you get 1 level in 4 different classes?
Can I retrain a multiclass feat? Furthermore can I retrain into a different multiclass feat?
Is normal (feat-based) multi-classing beneficial in D&D 4e? Is there a better way to achieve the same character design (a character with facets of two classes)?
