I Made an Aasamir cleric with good/healing domains and gave him GSF: Conjuration to make sure his planar summons would be top notch.
Finally, I get to 5th spell lvl and I get my first planar sumons: Lesser Planar Binding. I put it into my spellbook hoping it is at least equal to an undead of the same level.
Then I cast it

Lantern Archon. Great AC. More HP than me. Deals 1d2+2 damge and doesnt cast spells.....
Zombies do more damage vs tree smashers than this guy can do vs ANYONE
Did I do something wrong? Not read the summons guide correctly? Please tell me there is something that can be done about this.......
