==Normal Effects==
The library allows up to 30 people at a time to reduce their Death Debt. The level of your character will decide the amount of debt reduction the library offers.
The exact formula for Exp Debt Reduction is unknown but our observations are listed below. TP Debt Reduction is always 10% of Exp Debt Reduction.
It takes 2 minutes to reduce debt with , and it auto-repeats itself. That would be 5250 EXP and 525 TP reduced debt on a level 56 character every 2 minutes. Each level your Library is upgraded reduces the study time by 10 seconds. At the study time is 60 seconds.
Bonus XP/TP doesn't affect Library.
