Leveling Up

With a Bullpen of characters to play and a regular calendar of weeks and days, we can afford to expand the leveling up process beyond simply changing numbers on our sheets. Therefore we will use the following leveling up rules for our Cyfandil campaign. 

When a character meets the minimum XP requirements for attaining the next level of experience, he may seek out a mentor for training. Such training takes 1 week and 100 GP to rise to level 2, 2 weeks and 200 GP to rise to level three, and so on. The mentor so acquired must be at least the same level as the character wishes to attain. 

The time for training must be uninterrupted except for Sundays, which are a day of rest. Of course anticlerics may train on Sundays but must rest between Friday dusk and Saturday dusk.

The character may seek out an NPC or a higher-level PC, but in the latter case, all time and money must be paid and neither character may participate in other activities at the same time. 

On matching mentors to apprentices:

Fighting-men can train with dwarfs, elfs or other fighting-men. 
Clerics can only train with clerics; anticlerics with anticlerics. 
Magic-users can train with elves or magic-users. 
Dwarfs can train with dwarfs or fighting-men. 
Hobbits can train with hobbits or fighting-men. 
Elfs can train with elfs, or they can take training from both a fighting-man and a wizard. In the latter case, time and money costs apply separately to each patron, effectively doubling the character’s burden. 

PCs training lower-level characters: 

By the same token, a PC may take on an apprentice to train. The cost and time strictures are the same as above, but the master only collects a profit of half the total spent (and the attendant XP,) the rest of which goes to expenses. 

A master may only train up to two apprentices at the same time.  Clerics and anticlerics may only train one apprentice at a time.  

Note that a character does not need to use the same trainer for every level. He may switch freely from one to another for training successive levels. 

Note also that Lawful types will normally refuse to train Chaotics (but PCs can choose to do so.)

Once a character has been trained, then we can change the numbers on his sheet. The player rolls new hit dice and makes other level-based changes, such as the magic-user rolling for a new spell. 

Rolling hit dice:

At each new level, the player rolls all listed hit dice, totals them, and adds the constitution modifier for each one so rolled. 

If this amount is less than or equal to the current number of hit points, add one to that total. 

If this amount exceeds the current number of hit points, use this new total instead of the old one. 

In this way, the character will gain at least one hit point per level, and possibly many more. A high-level character will trend toward max hit points per die (but will rarely reach it.)
