I am wondering if it is possibile to reach the +17 modifier on an ability score. I am mainly keen on wizards, so I would like to know how it is possibile to reach 44/45 in Intelligence. At the moment i managed to reach 41, using magic items and bonuses of which I have knowledge of, but I guess I need your help.
The following are the bonuses I managed to find (at the moment I am considering a level 20th wizard)
- First of all, we start with a 20 in Intelligence (18 on the dice +2 of racial bonus)
- Extra ability score points from leveling up (4,8,12,16,20) so +5.
- Headband of Vast Intelligence (+6).
- Cast Wish 5 times, increasing the score of +1 each time (+5)
- Read the Tome of Clear Thought (the most expensive one) to have another +5.
Total:20+5+6+5+5 = 41
So this is what I've found. I am not concerned with the prices of the magic items or spells because actually I am not playing such a wizard. I am merely curious about how can a score like that be achieved.
