Increasing the Abilities of a Gen (CShaH)

__TOC__
A gen increases in hit points as its master increases in level, but there are other ways to improve the abilities of a gen as well. A gen's strength, damage, THAC0, and special abilities can be increased, and new abilities can be added.
Increasing a gen's capabilities is no light undertaking. Powerful rituals must be performed and the risk is great for both gen and sha'ir. Success is well worth the risk, though, and many sha'irs and gens undergo the rituals every year.
Before a gen can be increased, the permission of geniekind who govern his or her element must be sought. These genies are the only beings who can devise the rituals for individual gens and their sha'irs. To gain the favor of these genies, it is necessary to undertake a quest or to deliver some amount of gems or other valuables to the genies in question. These gifts are not demanded immediately; in most cases the sha'ir has until the next full moon to deliver the goods.
Even if the sha'ir is able to provide the genies with the item(s) that they want, he may still find his request for the rituals to improve his gen denied. The base chance for success in convincing geniekind to hand over the proper ritual is calculated as follows: (Level of sha'ir × 10) - [(Cost of ability to be added or improved) + (number of abilities already added to or improved upon for this gen × 5)]. The sha'ir must roll equal to or less than the number generated by the above formula on percentile dice in order to gain the rituals necessary to improve his gen.
Example: Fazil is a 6th-level sha'ir who wishes to add the ability to channel spells to his gen. His level multiplied by 10 is 60. The ability cost for channeling spells is 20, and the gen has already had three abilities added or improved. The final chance for success is (6 × 10) - [(20) +(3 × 5)]. This results in 60 - (20 + 15). Thus, Fazil has a 25 percent chance to increase the abilities of his gen.
If the sha'ir fails to sway the opinion of the genies, he will be stricken with some sort of punishment for his impertinence. Genies are not known to be overly kind when devising such punishments, especially for those sha'ir who repeatedly annoy them.
The first time a sha'ir fails to convince the genies that he needs to improve his gen's abilities, the genies will lower the "evil eye" on the character. This effect lasts for 1d6 days and cannot be removed before its duration is spent.
The second time the sha'ir bothers the genies and cannot convince them that his gen really needs a new ability, the effect is much more severe. The next time the gen goes out to find a spell, the genies will capture the familiar and keep it for 1d6 days before allowing it to return to the sha'ir. Usually the gen will be sent back with a message stating that the gen is in fine shape, and the genies really see no reason to meddle with the creature.
Penalties get much more severe from here, and genies have been known to go out of their way to cause trouble for the sha'ir who consistently fails to get permission to alter her gen. Genies find such sha'irs to be a bother and delight in tormenting them in subtle or not so subtle ways. Deprivation of magical abilities, physical disfigurement, shameful curses, and other debilitating fates may be visited upon sha'irs who try to overstep their bounds in the enhancement of their gen. Many are the tales of sha'irs who tried to force their will upon the genies in this manner. After repeated failures, many took their own lives rather than live with the humiliating punishments heaped upon them by geniekind.
