Basic tab

Low Bound: Specifies the position of the start angle twisting on the deformer’s local Y axis. Values must be negative numbers or zero. Use the slider to select values from -10.0000 to 0.0000. Default is -1.0000.
High Bound: Specifies the position of the end angle twisting on the deformer’s local Y axis. Values must be positive numbers. Use the slider to select values from 0.0000 to 10.0000. Default is 1.0000.
Start Angle: Specifies the degree of twisting at the low bound position on the deformer handle’s local negative Y axis. Use the slider to select values from -10.0000 to 10.0000. Default is 0.0000.
End Angle: Specifies the degree of twisting at the high bound position on the deformer handle’s local positive Y axis. Use the slider to select values from -10.0000 to 10.0000. Default is 0.0000.

Advanced tab

Deformation Order: Specifies the placement of the deformer node in the deformable object’s history. For more information about deformer placement, see Advanced deformer options.
Exclusive: Specifies whether the deformer set is in a partition. Sets in a partition can have no overlapping members. If on, the Partition To Use and New Partition Name options become available. Default is off.
Partition To Use: Lists any existing partitions, and a default selection Create New Partition. If you select Create New Partition, you can edit the New Partition Name field to specify the name of a new partition. Only available if Exclusive is on.
New Partition Name: Specifies the name of a new partition that will include the deformer set. The suggested partition name is deformPartition, which will be created if it does not already exist. Typically, you might put all your exclusive deformer sets in the partition named deformPartition. However, you can create as many partitions as you like, and name them whatever you want. Only available if Exclusive is on.
