Cross Classing in D20 Games - At What Cost?

During a game of "Conan" recently an interesting debate arose concerning Cross-Classing.

Cross-classing is the D20 mechanism by which (mostly) players earn levels in more than one character class, giving them the benefits of each at the levels they have earned. This allows, for example, a Fighter to also dabble in Druidic matters, or a Cleric to become (for whatever reason) particulalry sensitive to the ways of the Ranger.

The altruistic reason for allowing this is so that the rather artificial boundaries set by the D20/D&D "class" mechanic are blurred into a more "natural" model. The real reason is so players get buff in skills and natural abilities they otherwise would stand no chance of having at all.

It also buggers up the designed-in "nerfing" that each character class has to impose some limits on how players can behave in the game. Players, naturally, desire their characters to be renaissence men, women and werecreatures, able to turn their hands/paws to anything their little hearts desire without any hindering considerations of character background. Character classes are (partly) designed to build in reasonable limitations to character abliities (in the general sense rather than the specific D20 sense of that word). A Fighter cannot cast spells because he/she has been too busy learning to fight to pick up the knack, or has no latent ability with The Art. Cross-class that Fighter by giving him/her a level or two of Sorcerer and we have the beginings of a DM headache. Go to the cross-classing lengths some people do and that escalates into a migrane.

Which is not to say it shouldn't orta be. Cross classing makes otherwise boring character classes fun again. Of course, it does spread the perception that some classes, such as "Fighter" exsist solely to be used as a springboard for cross classing, which makes seeing a vanilla Fighter in D&D a rare thing. But with a bit of thought and a firm DM hand to keep it from getting stupidly daft, cross-classing is a bedrock part of D20 that I for one wouldn't want to see gone from the game.

The debate on Sunday arose in part because Conan encourages players to cross class. D&D has built in penalties for cross classing, but Conan removes those penalties and replaces them with benefits accrued from choosing a so-called racial "favoured class". Cross-classing incurs no penalties a-la D&D, and is much cheaper for the player in terms of Experience Point (XP) cost.

What the debate centered on (and it became quite heated I can tell you) was the XP cost that should be incurred for the new class levels.

D20 family rules that allow for cross classing usually (I don't know of one that diverges from this model, but I'm not widely read in D20-based rulesets) have it that your next character level costs whatever it costs to go to the "next level".

I'll explain that.

If you are, say, a 5th level Barbarian, and you've earned enough XP to ascend to 6th level barbarian but instead elect to "buy" a level of Thief, it costs 15,000 Experience Points (XP) according to the D20 escalation of XP costs per level. If you had bought that level of Thief for your inital character build at first level, it would have cost you 0 XP. If you had bought it for your third level it would have cost 3,000 XP. These costs are laid out in the Conan rulebook on page 40 (I think) and the D&D 3.5 Player Manual on page 9 (I think). In short, you pay the cost of the aggregate level you have achieved, but you buy the lowest "next level" you are entitled to.

One of the players felt this was monstrously unfair. He was buying a "first level", it should cost what a "first level costs" (that would be 0 XP of course, but he was under the impression it was 1000 to be fair). The DM was undecided on the matter. I felt, and still do, that it is a no-brainer. If you apply the cheaper costs, you invite hyper-characters skilled in everything under the sun, because although the maximum a player can gain is one level, the rewards at the character's other class suggested challenge rating (which is what the DM uses to set the reward levels) virtually guarrantee levels of XP remuneration that exceed the "Levelling Cost" for those low levels by many times. The rule is that a player may gain one level and retain enough XP to carry him/her to within one point of the next level. all other XP are lost. So far, so what? A player will end up earning 12 zillion XP and only being able to use 1000 of them. What's the big deal?

Consider the high-level player character who now goes out and about slaughtering otherwise puny enemies so he/she can level up in cheaper cross classes. The high levels of destruction the player can command far exceed anything an appropriate challenge for a low level character can bring to bear, making for a meaningless dice-fest.

Consider also the high-level Sorcerer who earns a bajillion XP, then asks Ron Innocent, unsuspecting DM if he may "burn some XP" as wishes for better stats, then buys a cheap low level in a cross class. The minmax potential is considerable.

I don't believe the D20 rule on this is in any way "broken". A level costs what a level costs. It is an abstraction anyway, and the extra class features that spring into being when a cross class is taken more than make up for any perceived "overcharging". But far more importantly, the "costs what it costs" version is easy to keep track of and reduces the anti-cheataccidental slip of the pen bookkeeping the DM must do to keep the game on track.

I would be interested in hearing what others think though.

I agree with you, totally. A level is a level, and being a seventh level fighter with one level of thief still makes you 8 levels total.

Indeed so - the game becomes completely unbalanced otherwise.

Of course, this problem gets to the heart of what I think is actually wrong with level-based systems in the first place, but in the context of D20 there's really no other way to do it without completely upsetting the playability of the game.
