You know, I must say I am pretty tired of hearing everyone argue about who gets this cloak casters or tanks?
Let's evaluate who would benifit the most and for the sake of this arguement I will omit the saves because everyone can benefit from saves.
Casters: INT
Paladins: STR WIS Haste
SK's: STR INT HASTE
Rangers: STR WIS Haste
Warriors: STR Haste
Rogues: STR Haste
Monks: STR Haste
Pretty obvious which classes benefit the most from this cloak.
