I've read on the summons guide that takeing cleric and good and/or evil domain would boost planar summons. I also came to belive this was one thing you could do to gain more boost to dragon knight summons as well. Maybe something has changed, or been worked out different but I got no changes in my build when I tested it.
My character was lvl 21 pure sorc, and I got dragon knight to go with my bonus greater conj feats and it is a nice summon with the buffs it gets. Then I decided hey why dont I try throwing a level of cleric in. It's not going to bother my too much to have 5 cleric levels and it my boost my summons abilitys. So I added cleric at 22 and choose good and evil domains because the only reason I was doing this was for extra boost. Well I summon my Solar with dragon knight and the summon is exsactly the same. All stats same number and before same ac/ab too.
Was the good/evil domain boost removed, or changed. Maybe something in my build is wrong not sure. Anyway just pointing this out, I've just deleveled and decided to go pure sorc to level 40 now. Unless this is just a temporary glitch in which case I have until level 35 to try again anyway.
Tested good/evil domain for solar.
Tried again and nothing. This time turned 28 took cleric domains good and animal. Summoned the solar and nothng changed. Then I relogged and came back summon solar and nothing different. Starting to think either somethings changed or possibly because I'm sorc it's effecting the bonus somehow. Anyway lvl 27 sorc 1 cleric didnt do anything for my dragon knight. So deleveled and went pure sorc.
Oh well, tried.
Oh well, tried.
