Pick an A and an N for this class. Both must be positive and cannot be greater than LVL.

Pick another class you know. The class chosen cannot be Custom group and must be a x1 multiplier class. ^{N}A represents the “Nth tetration of A”. For example, if ^{N}A were ^{3}2, it would equal a tower of 2 to the Nth power of 2 to the Nth power of 2 or 2^4 or 16. This can also be represented by Knuth’s up arrow notation as for example 2 ↑↑ 3 = 2^2^2 = 2^4 = 16.

Your "CL" and "LVL" for abilities is equal to your level times ^{N}A instead of your level. However, you get "Level:" abilities (and "picks") only up to your level as normal (it is *not* times ^{N}A). Any ability that cannot be material componented either will be either LVL^N or just LVL (DM discretion).

Warriors: Your base number of attacks is based on your level times ^{ N}A instead of your level. However, you cannot go beyond the bottom of the number of attacks chart.

Spell casters: Read on the ML= (level times ^{ N}A) line, but your max SL is based only on ML=(level). For example, a level 4 Tetrationer (N=3,A=2) emulating a Mage2 reads on the ML=16 line, but has only 1st and 2nd level spells (the max SL that a normal Mage2 has).

Priests: You turn undead using level times ^{ N}A. GGL powers that are LVL based use level times ^{ N}A, but you get Level: picks only up to your level.

Rogues: You get rogue points as if you were LVL=(level times ^{ N}A), but you read the rogue chart only down to your level (not times ^{ N}A).

Psionicists: Your LVL in PSP calculations is your level times ^{ N}A.

Level 18¶: You can trade 10000 TH, dmg, AC, saves, or hp to hang and “i” off of it respectively (as many times as you like). For example, if you have 10000^{3}, you could hang 3 “i” ‘s off of say TH to get iiiTH.

Level 36¶: The class chosen can be Custom group.
