Spell progression tables / Dragon disciple

Skaffen

Hello, haven't been able to find the Spell progression tables, manual gives useless stuff on reputation but not essential info like that. I'm particularly interested in dragon disciple vs. vanilla sorceror to see when the additional spells get deducted and how much it will hurt... are they posted online somewhere? Anyone soloed a DD yet?

Dragon Disciple just gets to cast 1 less spell on each spell tier, but they know the same amount.

Yes, but at what level is the spell deducted? Early on when you reach a new spell level so you have 2 instead of 3 or later so you stay at 5 instead of getting 6?

Senash

Everytime. When you gain a new level, you will be able to cast 2 instead of 3 and later on 5 instead of 6.

Ok, thanks, so it "hits" from the beginning.
