wait until you get to BG2 and duel at level 13 or 14 ranger abilities
max at level 16, priests max at 21 that is until BG2 expansion Throne of Bhaal
then every body maxes at Level 40 so if I were you don't worry about it now
you have A long way to go,so enjoy it.
In BG1 if you really want to duel you have to do it at level 6 other wise
you will never get enough experience points to ever be able to use your
ranger skills again remember in BG1 your cleric becomes 6th level at 20,000
experience points and 6th level ranger at 36,000 in order to use both skills
you'll have to take your prist to level 7 which is 35,000 experance points because you have to be one whole level higher than your original ranger in order to use your ranger skills and 89,000 is all the points you can have
until you add the BG1 expansion Tails of the Sword Coast then you'll gain a few more weapons but no bows or X-bows and your priest will be able to go to 125,000 exp points and only a level 7 cleric so even should duel now at level 5 you can never reach the 150,000 points it takes to reach level 8.
If I were you and wanted to be a Ranger/Cleric and I was only at level 5 in BG1
I wood start the game over and start as a Non-Human Multiclassed Cleric/Ranger
you'll be able to be a 7th level Ranger and an 7th level Priest before the end of the game.
If you start over the first 5 levels go fast the second time and you'll be back to where you are now in no time. Believe me I've played Bg1 and Tales of the Sword Coast close to 30 times and it's well worth the Restart.
