在Epic Level Handbook出版之前
FR独有的施法者进阶系统
根据这套系统，法术位会随着Epic等级的增加而增加……
由此计算出十级及十级以上法术位
但是想不起来……是怎么计算的来着了……
The character gains 1 spell slot per day whose level is one higher than the highest level spell he can already cast in a particular class. This benefit is only available if a character already has 20 levels in a spellcasting class. For example, if Elminster chose this benefit, he would gain one 10th-level wizard spell slot. If he chose it again, he would gain one 11th-level spell slot. If the character has a high enough ability modifier to gain a bonus spell for this spell level, he also gets that bonus spell of this new level. No spells exist of a spell level above 9th for wizards, sorcerers,clerics, and druids; 4th for paladins and rangers; or 6th for bards. However, these spell slots can be used for lower-level spells or metamagical spells.
