I've been scouring the boards and the rules: is there anything preventing me from buying multiple "sets" of spell-like abilities for my Intelligent weapon?
For example, it costs 1,200 gp to give my intelligent weapon the ability to cast enlarge person 3/day. Can I spent 2,400 gp to give it the ability to cast this spell 6/day? (Effectively three slots of each?
Same question, but with the Legendary Item's Intelligent Spellcasting ability: can I buy the spell-like ability more than once?
