hamper this paladin

[Plane Sailing]

Empowered Ray of Enfeeblement followed by a Web spell.

Heck, just hit him with a web spell! Even if he saves and has enormous strength it will still take him an age to get out of it unless there is fire around (and if the encounter is taking place in an area where you really don't want fire... they have been warned it is full of flammable gas, for instance...)

Cheers
