Caliber said:As far as I'm aware, the answer here is no. Remember, you only ever have 3 encounter and daily powers, even at 30th, and one of each is from your Paragon Path. So switching one of them out for your multiclass is a large percentage of their total.
silentounce said:I think you're wrong, take a look at page 29 of the PHB or page 143 of the DMG. PCs have far more than 3 encounter and daily powers even before hitting epic tier.
Kordeth said:The highest number of daily and encounter powers a character gets (not counting racial powers) is 4. They receive their fourth Daily at level 20 and their fourth Encounter at level 11. I wouldn't call that "far more than 3."
I must be misunderstanding the question. It sounds like you're asking if you can take several power-swap feats. As far as I'm aware, yes.
Edit: Unless you mean to take each one of the 3 multiple times. Then I don't know.
Have you tried making the character a Strength based Cleric who takes Kensai?
