I managed to access the new warden functions yesterday and thought it may be useful to show the code here;

First, set the player and playerattributes;

Player = Turbine.Gameplay.LocalPlayer.GetInstance()
PlayerAttributes=Player:GetClassAttributes()

Then the listener;

PlayerAttributes.GambitChanged=function()  
*What you want to happen*
end

PlayerAttributes:GetGambitCount() returns the count of current gambits
PlayerAttributes:GetGambit(i) returns which gambit (fist,shield,spear) is in slot i
PlayerAttributes:GetGambit(PlayerAttributes:GetGam bitCount()) returns the last used gambit - will throw an error if it is zero.

Have fun!
