ok so as i was fliping though my PnP book i was looking at all the calsses and i saw that if u rolled a clierc you could get some hting that made u a battle clierc and gave u like +1 to hit (somein like that) or a heal bot.
i was thinking i know we have some thing like that but u can get an enh that makes you a Battle bard or a healbot and not just war changer. lets u rouge for an example of enh.
Master theif
Rouge lvl 18
You can disable any trap in the game, find any door, and pick any lock.
You gain +5 stacking bonus to opin lock, search, spot, and disable.
and then you could opin up a enh line of disable-search-opin lock-spot enh.
or like if u wanter to be a back stab rouge
Master of the daggers
Your skill as a backstaber sets you apart from other rouges
You gain an extra 2d6 back stab damage.
u know i just taught it would be cool to add some thing along those lines. You can see a bit more of what i meen if u look in the class section of the Player Handbook tward the back of each classes section.
